ELECTRIC SYSTEM
Alternator
The engine is equipped with an alternator. To
ensure that the alternator with the built-on regulator
functions without interruptions the following
important points must be observed:
1.
Never switch off the main switch until the
engine has been stopped.
To do
otherwise
would be to ruin the charging
regulator.
2.
Do not mix up the battery connection
poles.
A plus sign and a
minus sign are
marked
on the respective poles. The minus pole is
connected up to the engine body. Cable shoes
should be greased and wall tightened.
3.
Re-wiring between the charging circuits
may not be carried out while the engine is
running.
Fit a Volvo Penta charging distributor
(accessory) on the alternator when more than
one battery is connected up.
4. Observe the following in the event the engine is started with an auxiliary battery:
Let the ordinary battery remain connected up. Connect the auxiliary battery to the
ordinary battery, plus to plus and minus to minus. When the engine has started,
remove the auxiliary battery but
do not
break the ordinary battery’s wiring circuit.
5. Do not use a rapid charging unit when the alternator is connected to the battery.
6. Before doing any work on the alternator equipment first disconnec
t
both the
battery cables.
7. In the event any electrical welding work is done on the engine or the installation
components, disconnect the charging regulator cables at the alternator and
insulate the cable ends.
8. Check regularly the belt tension and the cable connections.
