Electrical system

WARNING! Always stop the engine and break the current using the main switch before working on the
electrical system. Isolate battery charger, or other accessories mounted on the engine.
NOTE! NO ELECTRICAL SYSTEM AVAILABLE FOR ENGINES 420–721.
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 operation, the fuse may have
tripped. Reset the fuse by pressing on the button on
the fuse.
IMPORTANT! Always investigate the cause of
an overload before resetting the fuse!

Main switch

The main switch must never be turned off before the
engine has stopped. If the circuit between the gener-
ator and the battery is cut off when the engine is
running the generator can be seriously damaged.
IMPORTANT! Never break the circuit with the
main switch while the engine is running.

Electrical connections

Also check that all electrical connections are dry
and free of oxidation and that there are no loose
connections. If necessary, spray these connections
with a water-repellent spray (Volvo Penta Universal
oil).
