DESCRIPTION
ELECTRICAL SYSTEM
The electrical system is of the 12-volt type
and is fitted with a voltage-regulated alter-
nator. The starter motor is operated by
means of the ignition switch. This switch
i s also the main switch for the rest of the
electrical system. The cables to the head-
li ghts, parking lights, interior lighting, radio,
engine compartments and boot, however,
are not controlled by the ignition switch,
but can be switched on and off without
the ignition key being in position.
Lighting
The front lighting
consists of two head-
l i ghts (full and dipped beam), two extra
fog lights (on certain markets) together
with two turn indicators and a parking
l i ght. At the rear, the lighting consists of
two tail lights, turn indicators, brake war-
ning lights and reversing lights. There are
also two lights for the rear number plate.
The interior lighting consists of a roof
l i ght and one in the glove compartment.
On certain markets the vehicle is fitted
with side lights mounted on the sides of
the mudguards. Both the engine compart-
ment and boot are fitted with lights, which
function automatically when the bonnet
or boot lid is opened.
For replacement of bulbs, see pages 46,
47, 48 and 49.

Differences may occur for different markets.
The wiring diagram shows the fog lights connected
across the parking and dipped lights. On certain
markets they are connected across the parking and
main beam lights. On this occasion the brown lead
between the fog light relay (73) and the stop relay (18)
i s connected to 56 b. If the fog lights are connected
across only the parking lights, the lead goes to 56.
