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, ceiling lamps, a socket for a portable lamp and an alarm power supply circuit.
The electrical equipment of the car is protected by fuses installed in the mounting block.
The battery charging circuit, the ignition and engine start circuits, the windings of the dipped and main beam relays are not protected by fuses.
Before replacing a blown fuse, find out the cause of its blown and eliminate it. When troubleshooting, it is recommended to review the indicated subsection 9.2 the circuits that this fuse protects.
Until 1988, the fog lamps in the rear lights and the fog light indicator lamp were protected by the fuse number 17 of the mounting block. Since 1988, they have been protected by a separate fuse located in a plastic case in the wiring harness near the fog light switch. This fuse is 8A.
In addition, until 1988, the glove box lamp was not protected by fuse No. 15, but by fuse No. 2.
Mounting block
All fuses and auxiliary relays are installed in a separate mounting block (see fig. Mounting block (cover removed)), located in the engine compartment. In addition, through the mounting block, the wiring harnesses of the engine compartment are connected to the wiring harness of the instrument panel and to the rear harness. Conventional numbers of plugs in the connecting blocks of the mounting block are indicated in subsection 12.1. The scheme of internal connections of the mounting block is presented in subsection 12.17.
A mounting block of domestic production or Slovenia can be installed on the car. The mounting block, made in Slovenia, is non-separable and cannot be repaired. If internal connections are broken, it must be replaced with a new one.
Mounting blocks of domestic production can be disassembled and replaced with a block of printed circuit boards. It is allowed to solder wires to replace burned out current-carrying tracks on printed circuit boards, but only if this does not require disconnecting the printed circuit boards.
