ëhapter 7. Electrical system
Wiring and fuses
The electrical system is of the single-wire negative earth
type. The vehicle basic wiring diagram is illustrated in Fig.7-1.
Most electrical circuits are powered when the ignition is
switched on. Regardless the ignition switch position, the follow-
ing functions are available: horn, stoplight, cigarette lighter, inte-
rior lamps, inspection lamp, hazard warning flashers, exterior
lighting and main beam.
Most of the vehicle electrical circuits are protected by fuses,
which are located beneath the facia, at the left-hand side of the
steering column (Fig.7-2). There are no fuses for battery charg-
ing, ignition and engine start-up (starter and alternator) circuits,
main/dipped beam relay. Extra fuses 11, 12, 14, 16 are provided
in the additional fusebox to be used for alternative vehicle speci-
fications.
Before renewing a blown fuse, isolate and remedy the cause.
Before attempting to diagnose any electrical fault, refer to Table
7-1 to study the relevant wiring diagram protected by a failed
fuse.

* Pre-1996 vehicles were fitted with a voltmeter (protected by fuse No2) instead
of the relevant warning light in the instrument cluster.
In all wiring diagrams, covered by chapter «Electrical sys-
tem», the letters are used to denote the respective colour code:
the first letter stays for the wire colour Òode, while the second let-
ter - for the tracer colour code (Table 7-2).

WARNING. Always disconnect the battery negative lead
when making repairs on the vehicles or its electrical system.
When replacing fuses or checking wiring, never use fuses
other than those specified for a particular vehicle model as
it may damage current tracks in the fuse and relay box.
