Electrical diagram for connecting a VAZ 2105 carburetor

When the engine is equipped with a carburetor 21051-1107010, then instead of the control unit 21.3761 for the pneumatic throttle, a control unit 501.3761 for the carburetor solenoid valve is mounted.

The control unit 501.3761 is required to turn off the valve at a crankshaft speed of 1900 min-1, and turn it on at 1700 min-1

Mounting block

Replacement is carried out in case of failure. Before removing the distributor, you must disconnect the battery. But it is better to leave more complex work to professionals, since damage can sometimes only be determined using specialized equipment. Switches for headlights, direction indicators, cleaner and washer are combined into a block of steering column switches.

It often happens that drivers complain about the failure of recently installed dimensions, which, it would seem, still work and work. Its design consisted of: a coil, which is a voltage-increasing transformer; distributor with contact breaker; candles. The contact ignition system worked as follows. The only way to check the sensor […] November 25 The VAZ reverse light switch is located on the gearbox in its lower part. If it does not provide a circuit voltage of .5 volts when the engine is running, then it definitely needs to be replaced. If the arrow remains stationary, then the entire instrument cluster will have to be replaced. Thanks to this innovation, it will be much easier to survive in severe frosts.

The gearbox must be removed in the event of its failure, for repair work, as well as for any other work in which its presence will interfere. The relay regulator is responsible for the upper and lower threshold of the charging current supplied to the battery. If the device is working properly, the arrow should be at the beginning of the scale. Learning to read a car's electrical diagram. Part 1. Auto electrics.

Symptoms of a problem

that problems with electrical equipment can be determined by the following signs:

1. Charger. The charging light flashes and goes out, battery when the headlights are turned on. Knocks the regulator into the voltage jumper. When the ignition is turned on, the charging indicator lights up.
2. Movement. Spontaneously increases with movement speed. Jerking when moving at speed is small. Unstable idle. Power loss during acceleration.
3. Wiper. Windshield wipers are moving. They do not turn on jerkily or do not work in rainy conditions. weather wipers jerky.
4. Closures The ignition fuse burns out after No. 9 or burns out at the beginning. movement fuse No. 1. Fuse No. 7 burns when the dimensions are turned on.
5. Dashboard. When the power grid is under load, the devices begin to show incorrect Start.
6. engine values. The starter does not turn or turns weakly.
7. Lighting fixtures do not work.

Main wiring faults: short circuit or open. A short circuit causes fuses, relays to blow, and possibly even a fire to the devices. In the event of a breakdown, either a component or a system device, device, etc. fails. You need to be able to understand the electrical wiring of VAZ 2103, 2104 and other models, find and fix faults (author BORODA - MR.video).

Signs of trouble

If the car refuses to move, problems arise with electrical appliances or electrical wiring, this gives rise to troubleshooting by replacing faulty elements.

If the car does not start, first of all you need to check the flow of fuel into the carburetor or fuel injector frame.

If fuel is supplied, then the problem of the car’s refusal to drive must be looked for in the electrical system using an electrical diagram:

1. For a car with a carburetor, problems may arise with the distributor, coil, spark plugs, and also with electrical wiring. After checking the electrical circuit elements for serviceability, you need to replace the non-functioning components.
2. In a car with fuel injection, the problem may be due to a failure of the ECM (electronic engine management system). Thanks to it, signals coming from sensors are processed and commands are transmitted to units for execution (the author of the video is Alexander Skripchenko).

Problems are possible due to burnt contacts in the ignition switch. To troubleshoot, you need a diagram of the electrical equipment of a VAZ 2107 car indicating the elements that are consumers of the contact group.

Diagnostics of injection equipment

Electrical diagrams of VAZ 2109

The electrical component for the VAZ 2105 injector can often fail. For this reason, many owners of carburetor versions do not really want to switch to injection. Since the electrical circuit of the injection is more complex, it is almost impossible to find a breakdown without computer diagnostics. However, you can do some preliminary manipulations yourself.

For example, you need to check the spark plugs - this problem occurs often on the “five”. In addition, diagnosing the 21053 injector involves checking the resistance of the coils, inspecting the wiring and contacts. Quite often, the ignition and fuel supply begin to work incorrectly for some very trivial reason. It is worth checking the functionality of the oxygen sensor, first of all its contacts. For more serious diagnostics of this sensor, you will need an oscilloscope.

In general, if you have all the tools and a computer, you can diagnose the VAZ 2105 injector yourself. Quite a lot of recommendations have been developed in this regard, and given that most services are reluctant to work with “classics”, self-repair is even more preferable. Despite the more complex electronics, the VAZ 2105 injector remains the same easy to repair and universal machine.

What is included in the electrical circuit?

The VAZ 2103 or 21041 circuit, regardless of the ignition system used, includes the following elements:

• a battery whose negative output is connected to the body;
• starter;
• regulator relay;
• PSU - a block with fuses designed to protect equipment from short circuits and high voltage;
• a generator, which is one of the main components of the VAZ wiring;
• ignition switch.

On any VAZ car, the negative outputs from energy consumers are output to ground, namely, to the car body. The car body itself is an excellent conductor. But as for the wired connection, it should be borne in mind that it is provided only by positive wiring. Above is a VAZ 2104 and VAZ 2103 diagram with all electrical circuits and the designation of all elements, and below is a table indicating the purpose of all relays.
