Electrical System
WARNING!
Always stop the engine and break the current using the
main switches before working on the electrical system.
Isolate shore current to the engine block heater, bat-
tery charger or accessories mounted on the engine.
Main Switch
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.
IMPORTANT!
Never disconnect the current with the main switches
when the engine is running, the alternator and elec-
tronics could be damaged
Fuses
The engine is fitted with two automatic circuit breakers
(1). The circuit breakers cut the power if the system is
overloaded.
If it is not possible to start the engine or if the instrument
stops working while running, the circuit breaker may
have been activated. Reset by pressing in the circuit
breaker (1).
IMPORTANT!
Always investigate the cause of the overload. If the
fuse trips frequently, contact an authorized Volvo
Penta workshop.
