General information
The electrical equipment of the car is made according to a single-wire circuit. Negative output consumers are electrically connected to the body («weight»), which acts as a second wire.
The nominal voltage of the on-board network is 12 V.
To protect electrical circuits, fuses are used, the color of which corresponds to the protection current of the fuse. The health of the fuse is determined by the presence of a wire conductor connecting the contacts of the fuse.
Before starting work with any of the elements of the vehicle's electrical equipment, to prevent a short circuit and / or fire during work, disconnect the wire from the negative terminal of the battery.
