Electrical System; Wiring Diagram - Volvo PV 544 Instruction Book

Electrical system

. The electrical system is of the six-volt type and is fitted with a voltage control
generator. The starter motor is controlled from the instrument panel by means of
the ignition key. This key also forms the main switch for the rest of the electrical
system. The cables to the headlights, parking lights and internal lighting, however,
are not taken over the ignition switch but can be switched on and off without the
ignition key being in position.
Lighting
The lighting on the vehicle consists of two headlights (full and dipped) together
with two combined flasher and parking lights. At the rear the lighting consists of
two tail lights including flashers as well as combined lamps for the tail lights and
the brake warning lights. Internal lighting consists of a roof light above the rear
view mirror.
See pages 42—44 concerning replacement of bulbs.
Fuses
The electrical system is protected by means of fuses fitted in a fusebox to the left
on the bulkhead under the hood. When replacing a fuse, be sure that you use a
fuse of the right rating. If one of the fuses should blow repeatedly do not fit a more
powerful fuse. Instead, take the vehicle to a workshop for a check of the electrical
system.
