Electrical System
The engine is equipped with a 2-pole electrical system
and an alternator. System voltage is 12V or 24V.
WARNING!
Always stop the engine and break the current using the
main switches before working on the engine.
Main switch
IMPORTANT!
Never disconnect the current with the main switches
when the engine is running, the alternator and elec-
tronics could be damaged.
The main switches must never be switched off before
the engine has stopped. If the circuit between the alter-
nator and the battery is disconnected when the engine
is running, the alternator and electronics can be dam-
aged. For the same reason the charging circuits must
never be re-connected with the engine running.
Fuses
The engine is equipped with a 10 A circuit breaker
which cuts the current if overloaded.
The circuit breaker is located on the left-hand side of
the engine

.
The engine stops if the fuse trips. If the circuit breaker
trips frequently, an authorized Volvo Penta workshop
should be contacted to investigate the cause of the
overload.
Electrical Connections
Check that electrical connections are dry, free from
oxide, and that they are securely tightened.
