Electrical System - Volvo Penta D2 Series Operator's Manual

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.
Maintenance: Electrical system
Main switch
The main switch must never be turned off before
the engine has stopped. If the circuit between the
generator and the battery is cut off when the engine
is running 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.
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).
