ELECTRICAL 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.
The main switch must never be
switched off until the engine has
stopped.
O
therwise
the charging regulator will be
ruined.
2.
The battery connection poles must
never be mixed up.
A plus sign and a
minus sign are
marked on the respective
poles. The minus pole is connected to
the cylinder block. The cable terminals
should be greased and well tightened.
3.
Switching 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 whenever the
engine is started with an auxiliary
battery:
Let the ordinary battery remain
connected. 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.
