General information
The car's electrical equipment is made using a single-wire scheme. The consumers are electrically connected to the body ("ground") with a negative terminal, which functions as the second wire.
The nominal voltage of the on-board network is 12 V.
Fuses are used to protect electrical circuits, the color of which corresponds to the fuse protection current. The serviceability of a fuse is determined by the presence of a wire conductor connecting the fuse contacts.
Before starting work on any of the vehicle's electrical components, to prevent short circuits and/or fires during work, disconnect the wire from the negative terminal of the battery.
