Electrical System
The engine is equipped with a 2-pole electrical system
and an alternator.
WARNING!
Always stop the engine and break the current using the
main switches before working on the engine.
IMPORTANT:
Contact a Volvo Penta dealer for information if any arc
welding will be performed on the application.
Arc welding can cause damage to the engine and the
electronics.
Main switch
IMPORTANT:
Never disconnect the current using the main switches
when the engine is running or by disconnecting the
battery cables.
The alternator and electronics could be damaged.
The main switches must never be switched off before
the engine has stopped. If the circuit between the
alternator and the battery is disconnected when the
engine is running, the alternator and electronics may
be damaged. 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.
