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, battery charger, or accessories mounted
on the engine.
The engine is equipped with a two-pole system electrical system which means that the voltage (minus) is re-
turned directly from the starter motor minus terminal with the battery negative lead. Individual components on the
system return voltage to the starter motor minus terminal via separate cables.
Fuses
The engine has automatic fuses located in the junc-
tion box. The fuses break the current when there is
an overload in the electrical system.
If the engine cannot be started or the instruments
stop operating during running a fuse can have
tripped. Reset the fuse by pressing on the button on
the junction box.
IMPORTANT! Always investigate the cause of
an overload before resetting the fuse!
The control lever with integrated Power Trim button
has a 5 A standard fuse in its cabling.
IMPORTANT! Always carry extra fuses on
board.
Electronic shift drives have a 5 A standard fuse (1) in
the cabling at the actuator.
Electrical connections
Also check that all electrical connections are dry and
free of oxidation and that there are no loose connec-
tions. If necessary, spray these connections with a
water-repellent spray (Volvo Penta Universal oil).
Main switch
The main switch must never be turned off before the
engine has stopped. If the circuit between the genera-
tor and the battery is cut off when the engine is run-
ning the generator can be seriously damaged. For the
same reason charging circuits must never be
switched over while the engine is running.
IMPORTANT! Never break the circuit with the
main switches while the engine is running.
