Electrical system
Changing batteries
Observe that when changing batteries, both should have
the same capacity and be the same age.
Batteries must be connected with the correct polarity. Incor-
rect connection will seriously damage the electrical system.
Do not disconnect the batteries while the engine is still run-
ning.
Make a practice of always remove the ground connection
(negative terminal) first and connecting it last when chang-
ing batteries. In this way, you will avoid the risk of shorting
with tools between the positive terminal and the battery box,
for instance.
Clean the battery poles and the battery lead terminals be-
fore connecting them. After connecting them, they must be
treated with anti-corrosion agent.
Battery boxes in various designs are available from Volvo.
Battery installation may also have been carried out by the
coach-builder. Battery box and rapid charge connector (see
next page) may therefore be located and designed differ-
ently to that illustrated.
If a battery lead terminal has been connected incorrectly,
the battery pole must be reamed. Otherwise, the contact
surface between the battery pole and the terminal will be
insufficient when the terminal is reconnected correctly. It
also increases the risk of oxide forming in the space be-
tween the top of the battery pole and the terminal.
