Maintenance. Electrical system
Electrical system
The engine is equipped with a -pole electrical system and an alternator. System voltage is 4V.
WARNING!
Before any work is done on the electrical system, the engine must be stopped and the current
cut by switching off the battery isolator. Shore current for engine heaters, battery chargers or other auxiliary
equipment connected to the engine must be disconnected.
Main switches
The main switches must never be disconnected
before the engine has been stopped. If the circuit
between the alternator and the batteries is discon-
nected when the engine is running, the alternator and
electronics can be damaged. The charging circuits
must never be re-connected with the engine running,
for the same reason.
IMPORTANT!
Never disconnect the current with
the main switches when the engine is running.
Electrical connections
Check that electrical connections are dry, free from
oxide and that they are securely tightened. Spray
these connections as necessary with water-repellent
spray (Volvo Penta universal oil).
