A combination switch is used to switch the main circuits (lock) ignition, consisting of a contact part and a mechanical anti-theft device with a lock. The outdoor lighting and fog light switches are integrated into the outdoor lighting control unit.
The switch for the operating modes of the electric fan of the interior heater, the rear window heating switch, and the alarm switch are located on the overlay of the instrument panel console. The switches for headlights, direction indicators, wiper and washer are combined into a block of steering column switches. High power consumers are switched on through electromagnetic relays.
Attention! Carry out any work on the vehicle's electrical equipment only with the battery disconnected. Disconnect or connect the battery only when the ignition is off. When checking the circuits of electrical equipment, it is forbidden to short to «mass» wires (check the continuity of the circuits «for a spark»), as this can lead to failure of electrical components. It is forbidden to use fuses that are not provided for by the vehicle design or designed for a higher current, and also to use wire instead of fuses.
Attention! When replacing fuses, it is forbidden to use screwdrivers and metal tools, as this can lead to a short circuit in the circuits of electrical equipment. It is forbidden to disconnect the battery while the engine is running in order to avoid damage to the voltage regulator and elements of the vehicle's electronic equipment. In order not to fail the diodes of the rectifier unit, it is forbidden to check them with a megohmmeter or a test lamp supplied with a voltage of more than 12 V on a car without disconnecting the wires from the generator. It is necessary to check the insulation resistance of the generator stator winding with increased voltage on the generator removed from the vehicle, with the stator winding terminals disconnected from the rectifier unit. When carrying out electric welding work on a car, it is necessary to disconnect the wires from the battery terminals and the outputs of the generator and controller.
Attention! Do not touch the elements of the ignition system and high-voltage wires while the engine is running. Do not run low voltage wires in the same bundle as high voltage wires. Regularly clean the battery terminals and wire lugs from oxides and dirt. When recharging the battery with a charger, disconnect the wires of the electrical equipment from the battery terminals.
