Volvo 164 Owner's Manual - page 35
TECHNICAL 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 is
also the main switch for the rest of the
electrical system. The headlights, parking
li ghts and interior lighting, however, are
not wired via the ignition switch so they
can be switched on and off without switch-
i ng on the ignition key.
Lighting
The front lighting on the vehicle consists
of two headlights (full and dipped beam)
together with two turn indicators and park-
i ng lights.
At the rear, the lighting consists of two tail
li ghts, turn indicators, brake warning lights
and reversing lights. There are also two
lights for the rear license plate.
The car is also fitted with marker lights
mounted on the side of the fenders.
The interior lighting consists of a roof light
and one in the glove compartment.
The engine compartment and luggage
compartment also have a light which goes
on automatically when the bonnet or lug-
gage compartment lid is opened.
Concerning replacement of bulbs, see
pages 52-55.

Differences may occur for different markets.
The wiring diagram shows the foglights connect-
ed across the parking and dipped lights. On cer-
tain markets they are connected across the park-
i ng and main beam lights. On this occasion the
white-red lead between the foglight relay (73) and
the stop relay (18) is connected to 56 b. If the
foglights are connected across only the parking
lights, the lead goes to 56.
