Signs and causes of malfunction

To begin with, we will analyze signs of problems in the work of electrical caps.

Signs

By how "symptoms" you can define a malfunction:

1. The car does not start and does not go. The causes of the malfunction can be a set starting from the discharged battery and ending with the resulting generator device.
2. The machine starts and can move, but some nodes and systems function incorrectly.
3. The battery indicator flashed on the car dashboard. The fault may be associated with both the battery (discharge, a drop of tank or damage) and the operation of the generator device.
4. Optics are incorrectly function. Light headlights are weak, but it enhances when the gas pedal is pressed. Maltages can be due to the generator fault.
5. Certain electrical appliances do not work. For example, lighting in the cabin or heating device rear glass. The reason may be in damage to the chain wires or the failure of the fuse. Block diagnostics required.
6. The side indicators of turns do not function. The reason should be sought in electrocopy and fuses.

The reasons

1. Filed out plates AKB 2. Burning fuse VAZ 2106 3. Torn generator belt 4. Damaged high-voltage wires

For what reasons in the work of electrical equipment problems arise:

1. The discharge of the battery or its breakdown is associated with a decrease in the tank or the destruction of the inner plates. Malcy may be due to the fact that the AKB has worked out its service life. At the end of the operation of the operation, the internal components of the battery wear faster, especially if the car owner allowed errors when using the device. When the battery is discharged completely, it can be cheated, but it does not always allow to solve the problem. If the wear of the device is very large, then after the charge, the driver will be able to launch the engine, but as a result of the bus owner stops again, it will collide with the problem.
2. Problems with the generator. The malfunction of the device may be due to the failure of one of the design components of the generator set or the wear of its belt. If the diagnosis shows that there is not enough voltage on the electrical appliances, and accumulator battery Working, it is necessary to check the generator regulator relay, as well as the integrity of the belt. One of the signs of its wear is the voltage jumps, as well as a whistle from under the hood. The timing strap does not whistle can not. To replace the regulator, you will have to disassemble the device and its full analysis.
3. Damage to wire insulation, wiring break. If the insulating layer on electrical circuits is damaged, it leads to a current leakage. Accordingly, the electrical appliance will not receive a sufficient voltage level required for their power supply. In case of cliff wiring, the equipment will be impossible. Damaged electrocups are subject to replacement, and if the insulation layer is broken, the wire must be changed or wrapped over a re-tape.
4. Inoperable contacts. Almost all electrical caps have connectors for connecting. If their contacts are damaged, burn out or oxidized, this leads to the fact that the current cannot flow into equipment. When oxidizing, elements are cleaned, it usually eliminates the problem. If the contacts are damaged, then the only solution will be replaced the connectors. But in case of brave, the plugs are not replaced enough. It is necessary to find out the reason, since the burning of contacts speaks of voltage jumps in the power grid. If you do not fix the problem, the car owner will constantly face it after replacing contacts.
5. Breakdown relays or fuses. All items located in the mounting block are responsible for the operating condition of the electrical appliances. If they fail, damage or burn out, the operation of the equipment will be impossible. Detailed diagnostics and replacement of components failed. To search for a faulty fuse, use the scheme located on back side Block. As in the case of contacts, the presence of traces of burning on the fuses speaks of voltage jumps in on-board networkthat need to be eliminated. If the device is responsible for work fuel pump, His breakdown will lead to the fact that the engine launch will be impossible.
6. Malfunction of the ignition lock or other NW or BSZ elements - a traver, starter. With such malfunctions, run the motor will not be released. If the starter is defective, when you try to turn on the engine, the driver will hear clicks. The dashboard is usually activated, which indicate the indicators ran on it, but the motor does not start. It is necessary to perform alternate dismantling of all the structural components of the ignition system - the lock, the traver and the starter. These devices are subject to detailed diagnostics, displacement and replacement of components failed.
7. One of the causes of the malfunction of the electrical caps in which the motor may not start, is the damage of high-voltage wires of the ignition system. We are talking about those cables that are connected to the candles. If they are damaged, a sufficient high-voltage discharge cannot be received on the candles. As a result, problems arise with the start of the engine. If the power unit is started, but insulation is damaged on high-voltage wire, the motor will told. Problems can be solved by replacing cables. More details are the causes of problems are shown in the photo.

Practice shows that most faults in the work of the auto wiring is associated with poor quality compound.

On the nuances of repairing wiring when replacing one ignition to another can be found from the roller shot by Vyacheslav Kravchenko.

In such models, the principle of operation of the electrocups when starting the motor looks like this:

1. The driver inserts the key into the castle, after which turns it to the "Starter" position. This results in power supply to the device.
2. Generator installation comes into operation. A voltage comes from the device to the coil, this element is designed to form a high-voltage pulse. A low voltage current is supplied to it, which, as a result of transformation, receives high voltage. The discharge comes from the coil to the rubber.
3. By means of high-voltage cables, the device drive begins to push the crankshaft of the car motor. The latter makes a closure of contacts in a certain order, after which the discharge comes to the candle.

Depending on the type of car on the carburetor, classical or electronic ignition.

Classic ignition

Such a system is called contactless, it consists of:

• ignition switch, i.e. lock;
• coils;
• distribution mechanism;
• high-voltage cables;
• candles.

The switchgear function is to interrupt the electronicle of the primary winding on the module. After that, the mechanism distributes the voltage on the candles in a specific order. Thanks to the coil, the low-voltage current is converted to high-voltage. The purpose of candles is to fire combustible mixture In the cylinders of car engine.

On the designations of safety devices on the carburetor version of the car, you can learn from the video published by the Avtoclub_22 channel.

Electronic

If the machine is equipped with an electronic ignition system, then in it in the area of \u200b\u200bthe chain between the traver device, as well as the coil is located the switching mechanism.

BSZ consists of:

• switching device;
• switch, i.e. castle;
• coils;
• distribution device;
• high-voltage cables for which the discharge comes on the candle;
• candles themselves.

Thanks to the distribution device, control pulses arrive at the switch device, this is done to appear the spark. After that, the signals are served alternately on all spark plugs. The main purpose of the switch consists in converting control pulses from the contactless device in the current, the latter is used to feed the coil to the primary winding. This contributes to improving the appearance of the spark, which is especially relevant for the power units operating on the depleted combustible mixture.

The diagnostics of the switching device is carried out using a spark. If a high-voltage signal does not receive an audit on the rubler, this indicates a switter fault. The device is replaced. But if the problem has not been solved as a result of repair or shift, then you need to perform the diagnosis of electrical caps and change damaged wires. Perhaps the reason should be sought in an increased resistance lived, it leads to the fact that the spark will be too weak.

VAZ 2106 with injector

Cars of later releases became equipped with injection force units. We will not consider the electricity of such machines, since it is almost identical to the above described above.

On the transfer of "six" from the carburetor on the injector and repair workoh, on the transfer of wiring, you can learn from the video from Sergey Kryuchkov.

Device Connection Electroscheme in such machines has undergone certain changes:

1. Cars became equipped with electric pumps used to increase the pressure level in the ramp. There is no such pressure in power units with carburetors, mechanical pumping devices are used in them.
2. The combustible mixture is formed directly in cylinders of the DVS. In classic versions, its formation occurs in the carburetor.
3. Added electrical nozzles, they are responsible for fuel injection.
4. Also, the electroshem is complemented by the ECM control module. The device is used to detect the moment at which the fuel mixture injection is required. In carburetry versions, it enters the cylinders when opening the inlet valve.

Injector systems are characterized by the presence of a large number of electronic components. If the engine does not start, the reason can be concluded not only in damage to the wiring, but not the working condition of the sensors.

Instructions for diagnosing and replacing wiring

When damaged the wiring scheme in the VAZ 2106, the voltage level diagnostics should be diagnosed in the on-board network, for this you need a test lamp with two connected wires:

1. One of the contacts "The Checks" connects to the minus terminal of the battery under the hood of the machine. You can use a mass, that is, any metal part of the body or engine of the car.
2. The second contact is connected to the connection of the diagnosed area of \u200b\u200bthe electrocups. It is important that it is located closest to the battery or a safety device.
3. If, as a result of the connection "The control" began to burn, the voltage in the electrocuprup is available. This suggests that the diagnosed part of the wiring in working condition.
4. The diagnostic procedure is produced in a similar way on the rest of the sections of the wiring.
5. If the check showed that the bulb does not light up, this indicates the lack of voltage in the chain. The cause of the malfunction must be sought between this point and the last point where the current was.

The VAZ channel 2101-2107 in the roller showed how the battery charge diagnostic procedure is performed.

Depending on the type of connection, the voltage in the chain may appear only after the ignition lock is turned on.

With a short closure, one of the search options is dismantling the safety device and connecting to the contacts of its tester jack (voltmeter or multimeter) or "checklists". When checking, other components of the electrical equipment system on the diagnosed area of \u200b\u200bthe chain must be disabled so that the voltage is missing. If you use a control lamp, then after connecting the contacts to the sockets, it is necessary to move the wires in different directions. If during the task of the task lamp began to burn, this suggests that somewhere on the site there is a closure. Most likely, the insulation of wires occurred.

Diagnostics of grounding is carried out to test the reliability of electrical appliances to the mass of the machine:

1. Open the hood and disconnect the battery. One of the contacts of the device, which is tested, must be connected to the mass, that is, the body or metal on the car.
2. The second contact is connected to the location of the connection or the ground point.
3. If, as a result of the connection, the "control" began to burn, this suggests that with the mass on the diagnosed area of \u200b\u200bthe chain, everything is in order.

User Roman Rostovchanin spoke about errors that cannot be allowed when checking the grounding of contacts.

How to find a damaged segment of wiring:

1. From the diagnosed segment of the chain, it is necessary to turn off the voltage. The wiring portion is checked by means of a lamp with a connected voltage source.
2. The two end of the wires from the light source are connected to different ends of the electrocups or to the positive output and mass of the machine. When the indicator caught fire, there are no breaks in the wiring. If the lamp did not turn on, then you need to look for damage damage.
3. Similarly, the ignition lock is diagnosed, the "control" is connected to its terminals for verification. When the switch is activated, the light source must turn around.

If the cause of the electrical appliance is in the presence of an open chain, then it is almost impossible to find a damaged area, because it is difficult to see oxidation on contacts or their damage difficult. To solve the problem, you can try to move the connected wire or re-connect the contacts. Sometimes it allows you to solve the problem. As for the replacement of the damaged section of the chain, it is simply necessary to cut the worn wire, and it is connected to a new one instead. The location of the compound is selected or shaved with a tape.

If you decide to completely change the wiring in the car, we recommend contacting the specialists.

If the malfunction lies in the fuse breakdown, then it is possible to determine such a problem visually. Wire breaking in the body of the details indicates the need to replace it. Changing the devices should use similar power fuses, the use of spare parts with other rates is not recommended. The fact is that for different sections of the electrocopy, a different level of protection is required. The power of the device is indicated on its housing. If the item fails, then it is necessary to find the cause before it is replaced. Most often, the fuses break due to short circuit, which is associated with a breakdown or wiring wear.

User Valery Potapenko in his roller gave recommendations for the search and replacement of fuses.

In the electrical caps of the machine can be used in the jumpers. They are used in the sections of the wiring, which is not protected by safety devices, for example, in the ignition system circuits. The main similarity of jumpers and fuses is that the diagnosis and other parts can be carried out visually. To check, you need to turn off the battery from the power, then dismantle the jumper and estimate its condition. If visual diagnostics showed the need to replace, the device changes.

How to prevent malfunctions in the work of the wiring?

What needs to be considered in order not to encounter problems in the work of the electrical caps:

1. The wire replacement procedure must be made when the electrical appliances and the battery are turned off.
2. Disable and turn on the contacts of the battery is allowed exclusively when the ignition is turned off.
3. When checking wiring, it is impossible to make closures, it can lead to a breakdown of electrical appliances.
4. Do not use metal tools to extract safety devices.
5. On the engine installed, do not disconnect the battery. As a result, the car owner may face the problem of the failure of the voltage regulator and other components of the chain elements.
6. If the operation of the generator unit's diode bridge is performed, it is not allowed to use a megoometer feeding from a network with a voltage of more than 12 volts.
7. When welding the body, the battery and the generator must be disabled. It is also necessary to disconnect from the power of the ECU if it is available.
8. It is not allowed to repair or replacing the wiring when the engine is turned off.
9. Periodically perform the recharging of the battery, as well as cleaning it with terminals.

The development of automotive vehicles is closely related to the evolution of mankind. The formation of transport has developed slowly, as self-propelled car is a complex complex of mechanical and electrical elements, where the main components are grouped: the body, chassis, engine and wiring, working in complete coordination with each other. Data Design and Device Subsystems ensure the effective functioning of the car using constructive features Elements and their purpose.

Scheme of electric equipment car VAZ 2106

The VAZ 2106 car was a real culmination of many years of innovative research and development. This is a machine with reliable mechanical and electrical devices. When developing VAZ 2106 Volzhsky specialists car factory Guided technical task to update and upgrade previous models to european standards Quality. Changes to the exterior, Soviet designers developed new design rear Lights, side signs of rotation and other elements. Commissioning on domestic roads The most popular and mass car VAZ 2106 was published in February 1976.

In addition to the change in the suspension and modification of the engine, the specialists paid attention to the electrical wiring in the car representing the system of color wires laid down side by side and associated with the insulating tape. The electrical circuit is part of transport and includes a circuit designed to operate the engine and a chain for transmitting electrical energy to lighting consumers:

• motor start system;
• battery charge elements;
• the ignition system of the fuel mixture;
• elements of outdoor and cabin lighting;
• system of sensors on the instrument panel;
• elements of audio alert;

The electric car system is a closed circuit with an independent power source. The current flows through the cable from the battery to the feed component, the current is returned to the battery through the metal case of the car, connected to the battery with a thick cable. Thin wires are used for accessories and relays that require low power.

Using modern design and ergonomics of the location of the controls, the plant specialists supplemented the design of the VAZ 2106 by an alarm, stealing control of janitor and windshield washer. For effective display of technical indicators, the instrument panel equipped the lighting retake. Low level The brake fluid was determined by a separate test lamp. The luxury configurations of the model were supplied with a radio reception, heating of the rear window and a red fog lantern under the rear bumper.

For the first time on the models of the Soviet Auto industry, the rear lights are combined into a single case with a rotation pointer, overall fire, a stop signal, a reversing fire, a catapho, structurally combined with a license plate lighting.

Wiring diagram VAZ 2106 (carburetor)

Through the car runs the complex network of wires. To avoid confusion, each wire connected to a separate element has a different color designation. To track the wiring, the entire scheme is reflected in the car maintenance manual. The wire bundle is stretched over the entire length of the body from the power unit to luggage compartment. The electrical equipment connection scheme is simple and understandable, requiring explanations in case of problems with identifying elements. Color marking Used to facilitate the switching process of electrical consumers, the detailed connection of which is indicated in the schemes and manuals.

Table: Description of the electrical circuit

The electrical equipment system is made according to a single-wire diagram, where the negative terminals of the sources of electricity consumption are connected to the car body performing the "mass" function. Current sources are alternator and rechargeable battery. Starting the engine provides a starter with an electromagnetic trailer relay.

For the operation of the power unit with the carburetor uses a mechanical system electric ignition. The operation of the system begins with the creation of a magnetic field inside the core of the ignition coil forming the energy tank that will be used to excite the spark on the ignition candle through the high voltage wires.

Activation of the entire startup process electrical circuit Starts with the ignition lock and contact group, controlling the car ignition system, lighting system and light alarm.

The main devices of outdoor lighting are the headlights of the Middle and Flow Light, turn signs, rear lights and lighting registration sign. Two slaves are used to illuminate the cabin. In addition, there are door switches on the front and rear door racks. The electrical wiring of the instrument panel includes a complex of elements for the driver alert about the technical condition of the vehicle: tachometer, speedometer, temperature pointers, fuel level and oil pressure. To illuminate the instrument panel at night six are used control lamps.

The main characteristics of the circuit of electrical wiring:

• activation of the electrical circuit through the ignition lock;
• switching current consumers through the fuse block;
• connect key nodes with source of electricity.

Wiring diagram VAZ 2106 (injector)

The disadvantage of the mechanical ignition system with a carburetor engine is to use low-voltage interruption points on the primary winding of the ignition coil. Mechanical wear of contacts on the camshaft cam, their oxidation and burning of the contact surface from constant sparking. Permanent adjustment To compensate for the wear of contact switches excludes mechanical changes. The power of the spark discharge depends on the state of the contact group, and poor sparking leads to a decrease in engine efficiency. The mechanical system is not able to provide a sufficient service life of the components, limiting the power of the spark and the engine speed.

Table: Description of the electrical circuit of the injector

Electronic ignition was introduced to solve the problems of the mechanical ignition system. In the source systems, the contact switches replaced the sensor using the Hall effect and reacting to the rotating magnet on distributional. On new cars removed mechanical system ignition by replacing it on electronic system Without moving parts. The system is fully controlled on-board computer. Instead of the ignition distributor, an ignition module that serves all spark plugs is introduced. Together with the development of transport technologies automobiles Supplied fuel injection system that requires accurate and powerful education of the spark discharge.

The injector system on the VAZ 2106 for fuel supply was established since 2002. Previously used mechanical sparking did not allow to raise performance features Motor. An updated injector power supply scheme uses a scheme electronic control Works of the whole system. The electronic unit (ECU) manages many processes:

• fuel injection through the nozzles;
• monitoring the state of fuel;
• ignition;
• state of exhaust gases.

The functioning of the system begins with the testimony of the crankshaft position sensor, signaling the write about the spark of the candle. The electronic injector circuit differs from the carburetor model, assuming the inclusion in the car system of various electronic devicestransmitting signals about physical and technical parameters. Due to the presence of numerous sensors, the electronic injector circuit works steadily and stable. After processing all signals and parameters from sensors in the internal memory of the microcontroller, it is managed by the work of the actuating elements of the fuel supply, the moment of formation of the spark.

Podcast wiring

The main part of the electrical wiring is located in the engine compartment, where the main elements, electronic and mechanical car sensors are placed. A significant amount of wires reduce the overall aesthetic view of the motor, joined by the plural of cable wiring. For convenient maintenance of mechanical components of the engine, the manufacturer places the wiring into a plastic flaw, eliminating its overstraphing of the metal elements of the body and hiding it in the body cavities outside the field of view so that it does not distract attention from the power unit.

Under the engine hood, there are many auxiliary elements consuming or generating electric energy As a starter, generator, sensors. All devices are interconnected in a definitely and in the manner reflected on the electrical circuit. Wires are fixed in a safe and inconspicuous place, which eliminates their winding on moving chassis and motor elements.

Inside the engine compartment placed ground wires, a dense connection of which is permissible only on a smooth metal surface. Reliable contact of grounding through the car body provides a single return circuit from the minus terminal of the battery, which is a "mass" of the vehicle. The cables assembled in the beams from the sensors are laid in a protective cover, providing insulation from heat, liquids and radio interference.

In the wiring system placed in open space, includes:

• battery;
• starter;
• generator;
• ignition module;
• high-voltage wires and spark plugs;
• numerous sensors.

Wiring harness in the cabin

Thanks to the electrical wires, all sensors, nodes and dashboard Function as a single mechanism, providing a single task: uninterrupted transmission of electrical signals between interconnected elements.

In the cabin there is a majority of elements motor vehicleproviding process management, control of their implementation and diagnostics technical status Sensors.

Controls automotive systemslocated inside the cabin include:

• panel of control and measuring devices and its backlight;
• external lighting elements of the roadbed;
• turning alarms, stop and audio alert;
• salon lighting;
• other electronic helpers like wiper, heater, radio and navigation system.

Wiring harness in the cabin provides connecting all the elements of the car through the fuse block, which, regardless of the amount of instruments, is the main element of electrical wiring in the cabin. The fuse block, located to the left of the driver near the torpedo, often caused serious complaints from the owners of the VAZ 2106.

With the loss of physical contact of any wire, the fuses are overheated, burning the fuse insert. This fact was the presence of a problem in the electrical circuit of the car.

Table: Designation and power of fuses in the VAZ 2106 block

Wiring harness is laid under carpet, passing through technological processes in the metal vessel of transport from the torpedo to the luggage compartment.

Features of the electrical equipment and replacing wiring VAZ 2106

Properly laid wiring around the perimeter of the cabin and under the hood does not require special attention and maintenance. But, after repair work, the cable can be shifted, its insulation is damaged, which will lead to a short circuit. Bad contact will lead to the heating of the cable and melting the insulation. A similar result will be with improper installation of instruments and sensors.

The long period of operation of the vehicle affects the state of insulation of wires, which becomes solid and fragile, especially under the influence of significant heat in the engine compartment. Damage caused by damaged wires is not easy to find. If damage is in open access without a patch, the repair is carried out without disassembling the wires.

When replacing one wire, you should designate the labels of the wires in the pads, if necessary, making the connection drawing.

The main stages of wiring replacement:

• new wiring harness for the VAZ 2106 model;
• disabled battery from the car network;
• panel analysis of the instrument;
• laying torpedoes;
• removal of seats;
• removing noise insulating coating for convenient access to the wiring harness;
• clear corrosion that can cause bad contact;
• at the end of the work it is not recommended to leave the bare wires.

The procedure for replacing the wiring should not be performed without the electrical circuit of the connection of the instruments in order to exclude confusion during installation work.

When replacing a separate wire, you should use the same color and size. After replacement, you should test the corrected wire with a tester connected to the nearest connectors on both sides.

Precautions

Before performing work, turn off the battery and insulate sharp edges of the technological holes in the car body in places where the wires will pass to eliminate the short circuit.

Faults of electrical equipment VAZ 2106

Elimination of C. electrical elements Requires special skills and compliance with simple rules:

• the system requires a power source;
• electrical devices require constant voltage;
• the electrical circuit should not be interrupted.

When turning on the washer stalls the motor

The windshield washer is equipped with a switch that controls the fluid power engine. A malfunction in the form of a stressed motor can be caused by grounding of the feed cable, corroded terminal, dirty and damaged wires. To eliminate the fault it is worth checking all these elements and eliminate disadvantages.

Contact ignition contact system

Probably causes of faults serve:

• burning / oxidation of the ignition distributor contacts (timber block);
• burning or even partial destruction of the ignition distributor cover;
• burning contact runner and its wear;
• failure resistance runner;
• condenser failure.

These reasons worsen the operation of the engine, affecting its launch, especially in the cold period. One of the recommendations is to stripping the contact group of candles and a runner. If this reason arises, the contacts of the timeline are subject to replacement.

Wearing the ignition cover causes the runner damage. In this case, the details are subject to replacement.

Another reason is the malfunction of the ignition dispenser's interference capacitor. In any case, the detail must be replaced.

Wearing the mechanical part of the tramblor causes the shaft beating, which is manifested in various contact clearances. The reason is the bearing wear.

Faults of the ignition coil

The motor start is complicated when the ignition coil is malfunction, which begins to heat up significantly when the ignition is turned off due to short circuit. The reason for the breakdown of the ignition coil is the long-lasting foundation of the coil under voltage disabled EngineWhat leads to winding winding and short circuit. Faulty ignition coil is replaced.

Schemes of electrical equipment of individual branches

Electrical equipment VAZ 2106 was subjected to insignificant changes. An audible signal appeared on the car without switching relay, the rear fog lantern. The luxury modifications were installed the rear window heating system. Most current consumers are connected via the ignition key, which allows them to work only when the ignition is turned on, preventing accidentally off or discharge of the battery.

Auxiliary elements work without inclusion of ignition when the key is turned to the "I" position.

The ignition switch has 4 positions, the inclusion of which excites the current in specific connectors:

• in the position "0" from the battery is also powered only on connectors 30 and 30/1, others are de-energized.
• in the position "I", the current is supplied to the connectors of 30-int and 30/1-15, while the "dimensions", the windshield cleaner, the fan system of heater heating, running lights and fog lights are located;
• in the "II" position to previously involved connectors, contact 30-50 is additionally connected. At the same time, the ignition system, starter, panel sensors, and "turn signals" turn on the chain.
• in the position "III" only the car starter is involved. At the same time, the current is available only to the connectors of 30-int and 30/1.

Stove electric motor speed control circuit

If the car heater is not functioning enough, then you should pay attention to the stove fan. Automotive heating technology is simple and available for analysis.

Table: Salon heater fan power circuit

The problem can be in bad contact, which leads to the fact that the fan stops working.

On VAZ-2103 and VAZ-2106 cars, a single-conducting scheme for inclusion of electrical equipment are applied. The second wire connecting consumers with electricity sources is a car body or mass. Rated operating voltage of sources and consumers of electricity - 12 V. However, the voltage in the electrical equipment system, depending on the specific conditions, can fluctuate from 11 to 14.5 V, and within these limits consist of their health.

The supply voltage to most consumers is listed through the ignition switch. The power circuit of these electrical equipment sites, the operation of which may be required under any circumstances, are always connected to the battery (regardless of the key position in the ignition switch). Such nodes include nodes protected by fuse 1 (see table).

The power supply chains of most electrical equipment sites are protected by fuses installed in the plastic block 31. It contains 9 fuses by 8 A and one (1st) - 16 A. The unit is located under the instrument panel on the left side of the steering column. On the VAZ-2103 there is also a 19-on-16 fuse to protect the fan electric motor. It is located in a separate package next to the fuse block. On VAZ-2106 cars there is an additional fuse box with six fuses, two of which (4th and 5th) at 16 A, and the rest on 8 A. Fuse numbers and circuit protected by them are shown in the table:

When you burn any fuse, you need to watch the chains that it protects, eliminate the malfunction that caused its brave, and then put a new fuse. It is not allowed to install homemade or any other fuses that are not provided for by the design of the car.

Some electrical equipment systems whose work is required in emergency situations is not protected by fuses.

This is not protected by fuses the engine ignition system so as not to enter an excess element into it that reduces the reliability of the system in operation. If the ignition system fails, the engine will stop working. The engine start circuit is also not protected in order not to reduce the reliability of the start. In addition, the battery charge chain is not protected by fuses, as the generator connects to the battery with a short wire and the injection of the fuse would complicate the scheme. Also not protected by the fuses of the winding relay on the inclusion of the near and far beam headlights.

On vehicles are used flexible low-voltage wires of the type PVA. These wires have elastic polyvinyl chloride insulation, resistant to oil, gasoline and operational temperature range from -40 to + 105 ° C. The flexibility of the wires is ensured by manufacturing conductive veins from a large number of soft copper wires. To facilitate the search for the required wire in the beams, the insulation of the wires is painted in different colors. In addition, strips of different colors can be additionally applied to the insulation surface.

When the current passes on the wires, the voltage drops and the heating of the wires occurs. So that the heating and the voltage drop did not exceed the permissible limits, it is necessary to choose the corresponding cross section Core conductors lived wires. The greater the power flows, the cross section of the wire veins should be more transverse. Therefore, there are wires with different cross sections: 16; 6; four; 2.5 and 1 mm 2.

The largest wire sections of 16 mm 2 are connected to the "mass" of the battery and the engine, as well as the starter with the battery. According to these wires, the current of the greatest force when starting the engine starter. The battery and the generator are connected by a wire with a cross section of 6 mm2, as it also flows a fairly significant current when charging the battery and with a non-working engine, when all consumers eat from the battery. The remaining wires have a cross-section of veins 4, 2.5 or 1 mm 2.

Wires are connected to electrical equipment sites and are connected using quick-release plug connections. The exception is the connection of the wires to the battery, to the clamp "30" of the generator, to the starter power bolt and to the conclusions low voltage ignition coils. These responsible connections, wire tips are clamped with nuts to maximize the reliability of the compounds.

For the protection of electrical compounds from water and dirt, the rear of the subharbones is closed with rubber covers. High voltage wiring tips are closed with protective rubber caps, coolant temperature sensors and oil pressure, terminal "+" battery and a "30" generator terminal. Also closed with caps of lamps of lateral indicators of rotation and lighting lamps of the registration sign.

To facilitate the installation, all wires on the car are combined into bundles. Bunchers are connected to each other with the plug connectors, which reduces the ability to confuse wires when mounting. There are six wires of wires: front beam, rear, bundle of the instrument panel, right and left beams of sweathers and side indicators of rotation and bug of battery wires.

The main bundle of wires - front. It has three branches. Two of them are in the engine compartment, and the third is in the cabin under the instrument panel. From the salon to the engine compartment, the wire bundle passes through rubber compressor And after leaving it branches. The right branch of the beam is laid on the shield of the front and the right sprinkle of the body, and the left - on the left mudguard. On the shield of the front and mudguards of the wires are attached with steel brackets, welded to the body, and plastic homutics. The fastening of the beam should be so that it is not too tightened, but also did not hang out, as it can lead to the wires of wires when changing and closing them with "mass".

In the car's cabin, the front beam passes under the instrument panel and has small branches that go to the fuse blocks to the switches, to the instrument, the ignition switch and other electrical equipment nodes.

The rear bundle passes back to the left side of the floor of the body and has branches to the lighting celements of the cabin and to the lighting lamp of the trunk. Branch to the right ceiling passes behind the rear transverse body of the body floor. The wires of the beam are attached to the floor of the body sticky ribbon and plastic homutics.

The lugs of the wires (black) connecting the layers with the "mass" are attached to the doors of the doors with self-tapping screws. The tips of the wire connecting with the "mass" of the fuel level index sensor are attached under the screws of the sensor and the right rear light.

During the years of production of VAZ-2103 cars, changes related to the replacement were made in their diagram. separate nodes and aimed at improving the quality of cars and saving wires. To serious changes, it is possible to replace the windshield washer on the washer with an electric drive and replacing the double-click switch on the trigger steering column.

Features of the scheme of cars VAZ-2106

On these cars, compared with the VAZ-2103, another design of the rear lights and lighting lanterns of the registration sign. The two fuse blocks are installed - the main 29 (application) and additional 28. Added relay 6 to turn on the headlights of the headlights. An alarm system has been entered, including rotation pointers using a switch 40 and a circuit switch 33. There is a separate lamp 67 to monitor the level of the brake fluid and the switch 41 with the regulator of the degree of lighting the instruments.

Recently, small simplifications were made in the VAZ-2106 car scheme. Thus, one beep is currently installed, and it turns on directly switch 43 without relay 24. The lanterns 48 of the open front door alarm system with switch 47 and the interrupter relay 66 of the parking brake lamp are not installed. Now, when you turn on the parking brake, the control lamp 57 is lit by permanent light.

The WAZ-2106 Electrical Equipment Scheme is required to find faults in electrical wiring and quickly eliminate them.

The entire electrical equipment complex is connected by single-wire type - negative terminals of outputs from current sources are connected to the "mass" directly to an element consuming energy. As a result, "Mass" in this scheme VAZ-2106 performs the role of a second connecting wire. The figure below shows full view Equipment circuits and car wiring.

The WAZ-2106 scheme at the electrical equipment level is especially useful for the owners of this machine, when there is a need to quickly find a malfunction in the electrical wiring system. Conducted valve adjustment on VAZ-2109? Check the wires!

In addition, the scheme is often used to uniformly connect additional elements and audio recruits. If you decide to replace or repair the lighting devices, the ignition system and other electrical equipment, using this circuit you will find the desired terminal and the current source. When the engine is detected, first check the tightening torque of the GBC bolts, and then check the wiring.

How are the main elements of the VAZ-2106 machine wiring elements?

The wiring of the machine is protected by fuses, which are mainly installed in the central and additional unit located at the bottom of the instrument panel on the left side next to the steering column. The chain from the battery to the terminals and samples closes when the ignition is turned on by the car.

Tip: When performing work on replacing or repairing lighting and wiring, be sure to disconnect the battery from the network. Relays, switches, rechargeable battery, candles and even winding relay in the lighting and fan switching system in the cooling system is not protected by fuses. When the brakes are pumped on the VAZ-2107, a similar problem may occur.

In case of damage to one of the chain elements, a fuse is triggered. If malfunctions occur in the main set of fuses in operation, the backups are included, which are additionally installed next to the ignition block. When a distinguished fuse is detected, it is not enough to replace it - it is necessary to study the wiring in detail and find out the reason for the combustion of this spare part in the VAZ-2106.
