The main feature electrical circuit classic cars The VAZ family is single conduct. Those. All negative conclusions of nodes and appliances are directly connected to the "mass" of the car, in fact, the function of the second wire.

Thanks to this constructive solution, the wiring of VAZ 2106 is made as follows:

1. The main electric circuits of the car are activated only through the ignition lock;
2. Electrical mechanisms responsible for safety are connected directly with the battery through the fuse block;
3. The housings of all major vehicles of the car are conductive.

CAUTION: Be sure to remove the minus terminal from the battery whenever you take out one or another item.
Random touch with metal tools terminals and housing will lead to a short circuit.

Egnition lock

When servicing the car with your own hands, it is often necessary to find out the reason for the failure of a power system.
It is best to search for failures to start from the ignition castle, since this device Performs several functions in the car:

1. Is the control mechanism of the ignition system;
2. Performs the role of a security and anti-theft system;
3. Allows you to transport a car with an alarm enabled.

The scheme indicates:

1. Battery with connecting minus terminals for mass (car body);
2. Electric starter with output "50" from the ignition lock through the start relay;
3. Generator;
4. Fuse block;
5. Egnition lock;
6. Starting relay.

At the Ignition Castle 4, when activated which is activated, switching:

1. In the "0" position, the battery from the battery is served only on terminals 30 and 30/1. All other systems are disabled;
2. The "I" position is powered by terminal 30-int and 30/1-15. In this mode can only work parking lights, windshield wiper, heater stove fan;
3. In the "II" position, the terminal 30-50 is added to the already connected. The ignition system, starter, instruments on the panel, overall lights and turns are activated;
4. In the "III" position, only overseas lights, beeps and wipers remain active. Power is supplied to the terminals 30-int and 30/1.

Additional (abnormal) devices and equipment

On some modifications of the car VAZ 2106 are set:

1. rear window heating system;
2. windshield washer equipped with electric drive;
3. middle Light Relay Plans.

Accordingly, that the wiring on the VAZ 2106 in such modifications is different. In particular, the power to these devices is supplied with a separate wire through the ignition lock. It can only be activated when the key is "I" and "II".

Reference: Since the washer tank is made of plastic, the electric motor receives a "minus" on the wire.
When replacing, do not forget to wear a protective plastic cover for contacts.

Features of the electrical network

Reference: If the current in one of the protected chains exceeds the permissible value, the safety thread melts and dispels the circuit. As a result, the wiring on the VAZ 2106, as well as the connected devices and devices will not be affected.

Additional fuse block protects:

1. chain on the cooling system fan electric motor;
2. chain of turning signs and alarm.

Almost all the classics models are traditionally installed by the standard contact type ignition system (CWS). The exception is 21065, where the non-contact transistor scheme is used, in which the gap of the primary winding power circuit is implemented using the interrupter mounted in the distributor. Below, we consider in more detail how the VAZ-2106 ignition system works and works.

Contact Ignition Contact System

In the design contact circuit The ignition includes the following components:

lock (switch);

coil (KZ);

breaker (MP);

distributor (MR);

regulators, centrifugal and vacuum (CP and BP);

candles (SZ);

high voltage wires (VP).

Ignition coil (KZ) with two windings allows by conversion low voltage Get high.

Mechanical interruption (MP) Constructively completed with a mechanical distributor (MR) in one case - rubber. It provides opening of the primary winding of the KZ.

Mechanical distributor (MR) In the form of a rotor with a contact lid, distributes current to candles.

Centrifugal regulator (CP) allows you to change proportion to the magnitude of the crankshaft rotation angle (UAZ). Constructively CP made in the form of two loads. In the process of rotation, they affect the movable plate on which the MP cams are located.

Vacuum regulator (BP) performs adjustments to the magnitude of the angle of ahead (COUND) depending on the load. When changing the position throttle valve (DZ) the pressure in the cavity for DZ is changing. BP reacts to the degree of discharge and adjusts the value of the CHURD.

Principle of operation of the contact system scheme

The VAZ-2106 ignition contact system works according to the following scheme. When contacting contacts in the interrupter, the low current enters the primary winding of the KZ. When the contacts are blurred, the high current in the secondary winding of the KZ is indicated, which is transmitted to the high-voltage wire to the MR cover, and then distributed to the candle.

The increase in crankshaft turns leads to an increase in the speed of rotation of the CR, whose weights are diverted to the parties under the action of centrifugal forces. As a result, a movable plate is moved, increasing the CHURD. Accordingly, with a decrease in the revolutions, the advance ange decreases.

Continated transistor ignition system is an upgraded version classic schemewhich uses the transistor switch (TC) included in the CZ primary winding circuit. Such a constructive solution allows you to significantly increase the period of operation of the traver's contacts by reducing the current of the primary winding.

Checking the Ignition System VAZ-2106

Prepare a crusade and flat screwdriver, a control lamp or tester, rubber gloves and passage. Before checking contact ignitionTurn on parking brake Or set the pads under the vehicle wheels.

First, carefully check the integrity of all system elements, as well as the reliability of connecting high-voltage wires on all areas. They should be tightly planted in the appropriate contacts.

Turn on the ignition and check the current flow into the system. To do this, connect one wire lamp or tester to the mass, and the second to the contact "+ B" coil. The lamp should be lit, and the tester show the voltage of more than 11 V. Turn off the ignition.

To test the high-voltage wire, wear the rubber gloves and pull the central wire from the cover cover. Install the work candle in the cable tip, and then press it to the mass of the metal part. Turn the ignition to turn the crankshaft. If at the same time there is a discharge on the candle, then the wire is correct. In the event that there are no sparks, you need to look for the cause of a malfunction in the rubble.

To check the performance of the traver, remove the lid and inspect it for any damage, as well as the integrity of coal contact. When defects are detected, the cover should be replaced with a new analog.

Look at the distributor rotor. The slider should not have any damage. Sometimes the housing of the rotor can punch to the ground. Check also the performance of the interference resistance installed in the rotor. When the slightest doubts appear, it is recommended to replace the rotor.

After that, it is necessary to monitor the presence of a gap between the contacts of the MP. First, install the crankshaft using a special key to a position in which the top end cam shaft shaft will be exactly in the center of the textolite pillow lever of the rotating contact. Measure the gap between the MP contacts, its given value is 0.35-0.4 mm. If necessary, perform the appropriate adjustment. After that, check the magnitude of the advance angle.

After performing the above actions and eliminates the identified problems or replacing damaged components, start the engine. If in this case the motor has not earned, try replacing the condenser, which is in the interrupter.

Useful advice

If the interference resistance established in the rotor of the traver, it can be temporarily replaced by a spring from a conventional ballpoint handle.

What if there was a breakdown of the ignition lock or wiring lock on the way and eventually the food does not go to the ignition coil? In this case, you can get to the nearest service center by connecting the emergency power supply using an additional wire. One end to connect it with the plus terminal of the battery, and the second with the "+ B" terminal of the coil. However, while watching there is no spark. If strong spark discharges appear, turn off the wire at once. So, the problem with wiring and this option is not suitable.

The electrical equipment of the VAZ 2106 is quite simple. Elements of this wiring are connected using a single-wire connection principle. That is, the negative contacts of electrical dishes are derived on the "mass" of the car. The connection between the wires is provided only by the plus conclusions.

Vehicle Wiring Device

Such electric wiring in the people is called classic for several reasons:

• starting the operation of the electrkets occurs directly through the ignition switch;
• the battery is connected directly to the fuse block;
• the housings that conduct the current are in key nodes.

Note: If one of the systems has failed, it is necessary to look for a breakdown first in the ignition lock or in contact groups.

Principles of Electrical Equipment VAZ 2106

There are four ignition lock modes. Each phase has different functionality:

1. Phase "0". In this mode, the power is obtained only wires 30 and 30/1. Other functions do not work;
2. Phase "1". Running lights, headlights against fog, wipers, engine stove;
3. Phase "2". Rotary signals, instrument panel and an incendiary system begin work;
4. Phase "3". At this stage starter starts vehicle.

Some VAZ 2106 cars have additional accessories, such as a heating complex, automatic washers and so on. The launch of these additions occurs in phase 1 and 2.

Emergency system, claxon, brake lights, cigarette lighter, the backlight of the devices work in constant mode, that is, regardless of the position of the key in any phase.

Safety unit - electrical wiring element. Unfortunately, it does not comply with the requirements established by modern specialists.

• the fuse and the nest are unreliable, which leads to burning;
• the prevention element is heated when used.
• it is very poorly affected by the nests that are near;

As a rule, purchased fuses are unreliable. Because of this, it is worth a regularly configure check.

On a note. On the VAZ-E 2106 used "bugs". They are dangerous that there is a fairly large risk of short circuit, which can lead to transportation of transport.

Therefore, in order to ensure greater safety, it is necessary to replace the "bugs" on the fuses of a knife type. Their features:

• stable connection with other elements;
• fusible element is smeared in polyvinyl chloride;
• reducing heating by heat loss using an expanded area of \u200b\u200bcontouring.

Egnition lock

Conduct work to replace the ignition system at home. But if you are not confident in your abilities, you can contact the service. The cost of repair will not be much big.

The ignition system consists of the following details:

• hull itself;
• current drive;
• kernel;
• roller;
• bushing for connecting contacts;
• block.

Thus, the device of electrical equipment VAZ 2106 is sufficiently simple and care for it will not be difficult even to beginners in the automotive business.

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 Pointers Turn 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 sprawled along the entire length of the body from power aggregate before 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.

The activation of the entire launch process of the electrical circuit begins with the ignition lock and contact group, controlling the car ignition system, the 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. Six control lamps are used to illuminate the instrument panel at night.

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)

Disadvantage of the mechanical ignition system with carburetor Engine Is the use of 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

To solve the problems of the mechanical ignition system implemented electronic ignition. 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 electronic circuit The injector 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 motor compartmentwhere 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 interior perimeter and under the hood does not require special attention and maintenance. But after repair workThe 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 problems with 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.

The main difference between the contactless system consists in the presence of a pulse sensor installed instead of a trambl. The sensor creates pulses by passing them to the switch, which generates pulses as in the primary winding of the ignition coil. Next, the secondary winding produces high voltage current by passing it to ignition candles in a specific sequence.

Middle Light Electrical Equipment Scheme

Headlights are important element Safety responsible for improving the visibility of transport during the day and night. For long operation The light emitting thread comes into disrepair, violating the operation of the lighting system.

Loss of lighting affects the process of night driving. Therefore, the lamp-rented lamp should be replaced to increase illumination. In addition to lamps, the causes of malfunction can be the switching relay and fuses. When troubleshooting, enable data items to the inspection list.

Running Pointers Connection Scheme

When creating a VAZ model 2106, the constructors included in the list of the necessary elements alarm system, turned on with a separate button and connecting all signal signals.
