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.
