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, lampshades, portable lamp socket and power supply circuit for emergency signaling.
The vehicle's electrical equipment is protected by fuses installed in the fuse box.
The battery charging circuit, ignition and engine starting circuits, and windings of the low and high beam headlight relays are not protected by fuses.
Before replacing a blown fuse, find out the reason for its burning and eliminate it. When searching for a malfunction, it is recommended to review the following subsection 9.2 circuits that this fuse protects.
Before 1988, the rear fog lamps and the fog lamp indicator lamp were protected by fuse #17 in the fuse box. Since 1988, they have been protected by a separate fuse located in a plastic housing in the wiring harness near the fog lamp switch. This fuse is rated at 8 A.
In addition, until 1988, the glove compartment light was protected not by fuse #15, but by fuse #2.
Mounting block
All fuses and auxiliary relays are installed in a separate mounting block (see Fig. Mounting block (the lid is off)), located in the engine compartment. In addition, the wiring harnesses of the engine compartment are connected to the instrument panel wiring harness and to the rear harness via the mounting block. The conditional numbers of the plugs in the junction blocks of the mounting block are indicated in subsection 12.1. The internal connection diagram of the mounting block is presented in subsection 12.17.
The vehicle may be equipped with a mounting block of domestic or Slovenian manufacture. The mounting block manufactured in Slovenia is non-disassemblable and cannot be repaired. In case of damage to the internal connections, it must be replaced with a new one.
Domestic assembly units can be disassembled and their printed circuit boards can be replaced. It is allowed to solder wires to replace burnt-out current-carrying tracks on printed circuit boards, but only if this does not require disconnecting the printed circuit boards.
