Most circuits are turned on by the ignition switch. Always on (regardless of the position of the key in the ignition switch) power supply circuits for sound signals, cigarette lighter, brake light, interior light, hazard warning switch (in emergency mode) and the portable lamp socket.
The vehicle's electrical equipment is protected by fuses (Fig. 7-1) installed under the instrument panel on the left side of the steering column. The battery charging circuit, the low and high beam headlight relay, the ignition and engine starting circuits are not protected by fuses. Fuses 11, 13, 14, 15 (Fig. 7-1) installed in the additional fuse box are not used.
Fig. 7-1. Fuses
Before replacing a blown fuse, it is necessary to determine the cause of its combustion and eliminate it. When searching for a malfunction, it is recommended to look at the circuits specified in Table 7-1 that this fuse protects.
