Comment. The electrical equipment of the engine management system is covered in a separate chapter («Engine management system»).
The vehicle is fitted with a maintenance-free 55 Ah battery. It ensures the operation of the starter when starting the engine, as well as the operation of the car's security system during parking, the operation of the electric door lock (central lock) and other electrical equipment when the engine is not running. When the engine is running, power is supplied from the generator. Part of the energy generated by the generator is used to recharge the battery.
For most of the consumers of electricity, the supply voltage will be supplied through the switch (lock) ignition. Switches and switches of the main and additional electrical equipment are installed on the instrument panel lining, on the center console of the instrument panel and on the steering column.
Power supply circuits for powerful electricity consumers (headlights, windshield wiper, heated rear window, engine cooling radiator fan, fog lights) switched through a relay. Also, through the relay, the windshield wipers, alarms and direction indicators are switched on.
Vehicle electrical circuit weight (except for the power circuits of the starter and generator) protected by fuses.
The rated operating current of the fuse is indicated on its body. In addition, the color of the fuse body corresponds to a certain current value:
- 5 A - beige;
- 7.5 A - brown;
- 10 A - red;
- 15 A - blue;
- 20 A - yellow;
- 25 A - white;
- 30 A - green;
- 50 A - red.
Fuses and relays are installed in the mounting block.
The electrical wiring is assembled in bundles of copper wires with multi-colored insulation.
Most of the electrical connections of electrical equipment are made on detachable blocks.
