SERVICING
This car is fitted with an alternator.
When changing the battery or when
carrying out work involving the electri-
cal system, the following should be ob-
served.
1. A battery connection to the wrong
terminal will damage the rectifiers.
Before connections are made, check
the polarity of the battery with a volt-
meter.
2. If assist batteries are used for start-
i ng, they must be properly connect-
ed to prevent the rectifiers from
being damaged.
The negative lead from the assist
battery for starting must be connect-
ed to the negative terminal stud of
the car battery and the positive lead
from the assist battery for starting to
the positive terminal stud.
3. If a rapid charger is used for charg-
i ng the battery, the car battery leads
should be disconnected.
A rapid charger may not be used as
an aid in starting.
4. Never disconnect the battery circuit
(for example, to change the battery)
while the engine is running, as this
will immediately ruin the alternator.
Always make sure that all the battery
connections are properly tightened.
5. If any electrical welding work is to
be carried out on the vehicle, the
ground lead and all the connecting
cables of the alternator must be
placed as near the welding point as
possible.
Replacement of bulbs
To obtain maximum lighting effect and to
forestall the chances of lights going out,
the headlight bulbs should be changed
every year, suitable during the autumn.
The replacement of bulbs in the various
li ghting units is shown on the following
pages. Make sure when fitting lamps that
52
the guide pin on the socket fits into its
corresponding recess.
When fitting bulbs, do not touch the glass
with your fingers. The reason for this is
that grease, oil or any other impurities can
be carbonized onto the bulb and damage
the reflector.
Changing roof light bulb
To change the bulb in the roof light, press
i n the catch in the lamp housing. This is
done with a screwdriver which is inserted
i n the opening on the right-hand side of
the housing. Then pull the lamp housing
out of its attachment and the bulb is ac-
cessible for replacement.
Replace bulbs for instrument lighting
and heater control lighting
Owing to the location of the bulbs, they
should be replaced by a Volvo workshop.
