VAZ 2107 is a rear-wheel drive car based on the VAZ 2105. This is one of the representatives of the so-called classics. Its release was completed in 2012. Produced in the sedan body. The electrical circuit of the VAZ 2107 is not much different from the circuit of the VAZ 2105.
Many car owners want not only to use the car, but also to understand how one or another of its systems works. For someone who is guided in the electrical circuit of 2107, it will not be difficult to find the cause of the problem and carry out minor repairs on their own.
Wiring diagram vaz 2107 carburetor
The electrical equipment of a car, schematically shown in the diagram, is called an electrical circuit. It graphically displays the links between elements. Pay attention to the color of the wires in the diagram, they reflect the real picture quite accurately. This means that if the wire is shown in yellow, then most likely it is actually yellow.
Electrical equipment VAZ 2107. Systems
The electrical circuit of the "seven" is single-wire, the body plays the role of "minus". This arrangement allows fewer wires to be used and greatly simplifies wiring. The electrical equipment of the VAZ 2107 carburetor is conditionally divided into the following systems:
Power supply
This system is represented by a generator and a battery. She is responsible for supplying power to all electrical appliances and electronic devices auto.
Generator
When the engine is running, electrical appliances are powered by an alternator. VAZ 2107 generators were produced in two versions with markings 372.3701 and 9412.3701. latest model is improved, since its rectifier unit is protected by a plastic box, the impeller is located inside, the size of the slip rings is reduced, which significantly reduces the wear of parts.
Accumulator battery
The battery is responsible for powering all devices when the engine is off. It also provides movement in the event of a generator failure, if the charge is sufficient. When choosing a battery, it is important to consider the type of engine (carburetor or injector) as battery performance varies for these engine types.
Starting the engine
The engine starting system consists of two elements - a starter and an ignition switch.
Starter
This is a device powered by electricity and is responsible for starting the engine. It works in this way: it rotates the shaft in an incremental fashion until the speed is sufficient to start. Starters in different models VAZ 2107 have some differences, so you need to carefully consider buying a new unit if the old one becomes unusable. You need to buy exactly the model that came with the car from the manufacturer.
Ignition
This system is a combination of devices that, in the process of interaction, provide the appearance of a spark that ignites the fuel in the engine. internal combustion... It is represented by three main elements - an ignition switch (or switch), a coil and spark plugs and many additional ones.
Ignition switch
Serves to supply current to the ignition system and to disconnect it from electricity. Made in the form of a lock with a special key. The system is simple - if the key is inserted into the lock and turned, the contacts close and the ignition is turned on, and when the key is pushed out, the contacts open and the system is de-energized.
Candles
These are special devices for igniting fuel. In gasoline engines, they are spark. A very high voltage (tens of thousands of volts) arises between the electrodes of the candle, as a result of an electric discharge, which ensures ignition.
Coil
This is a device that converts low-voltage current supplied from a battery or generator into high-voltage, and transfers it to candles. it important element ignition system, the failure of which will not allow the engine to be brought into working condition.
Lighting and signaling
The car has external lighting devices and those that are responsible for the light in the cabin. The lighting system is represented by the following elements - block headlights, taillights, a lamp under the hood, interior lighting, a lamp illuminating a license plate. Also the system includes mounting block and light switches.
Control devices
The dashboard of the car is equipped with scales by which it is possible to determine the correct operation of all systems of the car and to identify malfunctions. Even an inexperienced motorist must be able to read the readings of these devices. Even if you do not understand the machine at all, read the instructions and learn how to read the instrument readings on the panel, this will not only simplify your life, but save you from unnecessary expenses, because if you do not react in time to the error in the operation of any electrical element, you will have to make expensive repairs in the future.
Additional devices
it electronic devices without which the car can work. These include a wiper, power windows, glass and headlight washers, a cigarette lighter, and the like. Some car enthusiasts stuff their classics with different additional options, for example, install additional LED backlights, tune dashboard... This makes it possible to do even a simple inexpensive car stylish and modern.
The electrical diagram of the VAZ 2107 will become a reference for you if you plan to repair an electrician of a car yourself. It shows in detail how the devices work, the wires are color-coded and even a beginner in the matter of electrics can identify a malfunction and fix it. If you are still not confident in your abilities, then entrust the work to an experienced auto electrician and then you will be sure of the result.
The VAZ 2109 car for many years remained one of the most popular in the country. Not just popular, but also prestigious. In the social hierarchy, the owners of nines were not much lower than the owners of used Cadets and Jetts. One could argue with the reliability of the car, but since there was no alternative, the car filled the entire CIS and was even assembled by the nodal method in Finland, but this has little to do with the 2109 model.
Wiring diagram VAZ 2109
Like the whole car, the electrical equipment was not at the highest level, so the owners of nines should know the VAZ 2109 wiring diagram thoroughly. To do this, we have brought a factory diagram in good resolution, which can be used with amendments for the changes made from time to time.
This is a canonical nine diagram with factory markings and explanations. In principle, the circuit is quite simple, but the electrical appliances themselves caused difficulties, the problems with which we will talk about.
Major problems with wiring 2109
The biggest problem in the VAZ 2109 electrical equipment was the low quality of the components and the unsatisfactory build quality. Despite the fact that Togliatti, by tradition, blames suppliers for all mortal sins, we eventually have to take the rap, and as ordinary users, we should not be at all interested in why the spirals on double-strand lamps constantly burn out. rear lights... Also, we, in principle, do not care which factory made the housings for the fuse box - we only see the inadequate operation of the electrical equipment, when the right turn is turned on when the brake pedal is pressed.
And there are a lot of such examples. If the plant is not sure about the quality of the components, why then put them on the car. Therefore, rhetorical questions only lead to unnecessary vibrations of the air, and the problem is not solved. The above problem with stops can be solved quite simply:
The short circuits of the tracks of this board occur due to contamination of the contacts and tracks. Then the signal applied to the stop lamp can simply be redirected to the direction indicator lamp. This is fundamentally solved by replacing the entire board with a new one, but the new bar will not last as long as we would like due to poor sealing of the plafond from the inside. luggage compartment... It seems to be a trifle, but we are wasting precious time on solving trivial problems that are solved at the production level with the correct, not VAZ approach.
Improvements and fixes of factory errors
In the light of the above, the breakdown of the electronics control unit is very characteristic of the nine. The reason is very simple - its body simply passes water, dust and moisture in the form of condensation. Its very placement on the air intake shelf is not entirely clear, but there are also more significant disadvantages that can be eliminated with your own hands. The factory has provided a tiny groove for water to drain from the hull, but it constantly clogs up, the hull fills with water, and the control unit slowly and surely dies. It is not cheap, so such negligence of the designers defies explanation. There are two ways out of the situation - to constantly clean the water drainage channel, or to change the unit at least once a year.
It is also worth paying attention to the fact that the power wiring on the lower shelf of the radiator is constantly exposed to high temperatures. In addition, in this place, it is not protected from water and dirt in any way. This is also a difficult to explain point. Harness oversights include the harness under the mat next to the driver's seat. Moisture constantly accumulates there, and in order to remove it, you need to dry the floor, inevitably pulling this tourniquet. Of course, you cannot solve such a problem on your own - there is too much work to tighten all the wiring in the car.
Costs Special attention be given to the power terminals on the generator. They very often loosen, heat up, spark and melt the wiring. But this is not the worst thing. The wires can be short-circuited, but here it already smells burnt. Therefore, do not be lazy, but as often as possible check this node for tightening the terminals.
Insulation of wiring harnesses 2109
For the sake of isolating the harnesses, no one will disassemble half of the car, but on occasion it must be done for their own safety. Using the diagram that we placed at the beginning of the article, all the work will not take much time, but you will be sure of the quality of the wiring insulation. To do this you will need:
- Corrugated hose for electrical wires.
- Insulating tape.
- Cleaner for wires.
Before packing the old wiring into the sleeve, treat the wires with a cleaner, which is sold in aerosol cans. Further, following the instructions and checking the wiring diagram, we act like this:
- Disconnect the battery
- Disconnect the terminals and remove the harness.
- We treat it with an aerosol.
- We carry out a visual check of contacts.
- We put the tourniquet in the corrugation.
- We fix and seal the entry points of the bundle into the corrugation.
- We put the finished cable in place.
- Referring to the diagram, we connect the terminals.
Particular attention should be paid to sealing the harnesses where they come into direct contact with water or hot surfaces. Also, when assembling, pay attention to the integrity of the blocks and the condition of the contacts and terminals.
Thus, spending very little time, we save the wiring and get rid of unnecessary problems with short circuits. Keep an eye on the wiring and good luck on the road!
Introducing electrical circuits for the VAZ 2110 1996+ onwards For more active drivers, a 16-valve version with gasoline engine working volume of 1.5 liters. power of 94 hp, with a two-shaft cylinder head, providing increased power (69 kW) and torque (130 Nm), allowing the car to have improved dynamic qualities. A car equipped with such a motor has an index VAZ 21103, maximum speed is already 185 km / h, and acceleration to "hundreds" takes only 12.5 seconds. These modifications are increasingly common on the roads, as well as the 2-liter 150-horsepower versions of the VAZ-21106 CTi are quite economical, expressive and expensive. Still, because the Opel X20XEV engine with a twin-shaft 16-valve cylinder head and a point injection system allows you to accelerate to 205 km / h. With it, a hundred-kilometer barrier is overcome in just 9.5 seconds. There is also a combat 240-strong (!) VAZ-21107 "Rally" 2.0 V16 with a special roll cage built into the body. Its maximum speed is 220 km / h, and the acceleration time to 100 km / h takes only 7 seconds! But it is made by the piece, only by the orders of athletes, and it costs - like foreign rally cars: expensive (22 thousand dollars). I must say that some domestic tuning firms create (even without the use of expensive imported components) quite successful speed or, on the contrary, comfortable versions of the "top ten", the dynamics, the handling of which while driving is significantly improved.
There are also four-wheel drive versions of the "ten" sports or all-terrain orientation, but they are either experimental, or small-scale, and therefore expensive.

Ignition system diagram for VAZ 2110
The quality of its work depends on the serviceability of the components and systems of the car. Modern machines are crammed with electronics, so the electrical system requires a lot of attention. The article deals with the VAZ 2107, the signs of a malfunction, and also discusses the features carburetor engines and with an injector.
[Hide]
Symptoms of malfunctions
If the car refuses to drive, there are problems with electrical appliances or electrical wiring, this gives rise to troubleshooting by replacing defective elements.
If the car does not start, the first step is to check the flow of fuel to the carburetor or the fuel rail of the injector.
If fuel comes in, then the problem of a car's refusal to go should be looked for in the electrical system using an electrical circuit:
- For a car with a carburetor, problems can be with the distributor, coil, spark plugs, as well as with electrical wiring. After checking the elements of the electrical circuit for serviceability, you need to replace the non-working components.
- In a car with an injector, the problem may be due to an ECM failure ( electronic system engine control). Thanks to it, the signals from the sensors are processed, and commands are transmitted for execution to the units (the author of the video is Alexander Skripchenko).
Possible problems due to burnt contacts in the ignition switch. For troubleshooting, you need 2107 with an indication of the elements that are consumers of the contact group.
Carburetor engine
The operation of the engine with a carburetor has a classic scheme:
- When the key in the ignition switch is turned to the “Starter” position, the electronic system supplies power to it.
- The generator starts its work.
- The generator transmits electrical current to the coil. It serves to obtain high-voltage currents. The coil receives currents low voltage... Passing through the module, they are transformed into high-voltage ones and transmitted to the distributor.
- With the help of high-voltage currents, the distributor drive rotates crankshaft power unit... He, in order of priority, closes the contacts and applies an electric discharge to the candles.
The principle of operation is reflected in the wiring diagram of the engine with a carburetor.
Wiring diagram of the classics - carburetor Classic ignition
V contact system includes the following elements:
- switch;
- coil;
- distributor;
- high voltage wires;
- candles.
Thanks to the distributor, the primary circuit of the ignition module is interrupted, and then the high-voltage current is distributed in the desired sequence to the spark plugs. The coil converts the low voltage current into high voltage current. Candles ignite fuel mixture in the engine cylinders.
If the engine does not start when the ignition key is turned, then the reason may be as follows:
- An open in the electrical circuit between the generator and the coil. In this case, you need to check all contacts and the integrity of the wiring.
- Coil defective. It can be checked with a spark: remove the wire from the distributor and touch the metal part. If a spark appears during operation of the power unit, it means that the module is working properly.
- Break in the electrical circuit between the distributor and the candles. In this case, you need a slider located there, high voltage wiring connecting the distributor cover with the candles.
After identifying and eliminating a malfunction in the carburetor, the engine should start without problems if the other components of the car are in good working order.
Electronic ignition
On some VAZ 2107 models that were released after 1987, it was installed. Although the car was more expensive, it was in demand. The innovation consisted in the fact that an electronic switch was installed between the distributor and the coil.
The non-contact ignition system includes:
- switch;
- ignition switch;
- coil;
- distributor sensor;
- high voltage wires;
- candles.
With the help of the distributor sensor, control signals are transmitted to the switch for the formation of a spark and high-voltage pulses are distributed among the spark plugs. The function of the switch is to convert the control pulses from the proximity sensor into a pulse current, which is fed to the primary winding of the coil. Thus, it improves spark formation when the engine is running on a lean mixture.
The switch is tested with a spark. If, during the check, the distributor does not receive a high voltage pulse, then the switch is defective and requires replacement.
If after replacing the switch with new problem remained, then it is necessary to replace the wiring with a VAZ 2107. Most likely, the reason lies in the high resistance of the wires of the wiring, this entails a weak spark formation.
Injection engine
The injection engine has the following differences from the carburetor one:
- electric pump, which serves to increase the pressure in fuel system(there is no pressure in an engine with a carburetor, and the pump is installed mechanical);
- the fuel mixture is formed in the cylinder itself, and in the classic version in the carburetor;
- electric injectors are responsible for injecting fuel into the cylinders;
- the moment when the injection of the mixture is required is determined by the ECM (the mixture enters the carburetor when the intake valve is opened).
An engine with an injector has a large number of electronic components. The reason for the failure of the motor may be a malfunction of the sensors and wiring.
You can find a malfunction in a car with an injector yourself:
- disconnect the sensor by removing the connector;
- check the resistance of the sensor using a tester;
- compare the results obtained with the nominal data, which can be taken from the table in the instructions supplied with the car.
If a faulty sensor is found, it must be replaced.
Conclusion
Thus, it is clear from the article that knowing the principle of operation of the engine with a VAZ 2107 carburetor, in particular with a contact and contactless system ignition, and an engine with an injector, you can identify the cause of the failure vehicle set in motion if the reason is electronics.
Knowing the reason for the refusal and having experience renovation works related to electrical wiring, the driver will be able to fix his car on the road and return it to working condition.
