Generator Power
Note
: The boat's generator battery charger automatically monitors the
voltage level in the generator battery and recharges the battery when
necessary as long as the Generator Battery Charger circuit breaker on
the AC Control Center is ON.
Never turn the Generator Master Disconnect switch to OFF while the
generator is operating. Doing this can damage the generator or it's alternator
wiring.
Dedicating a 12-volt battery to the generator provides an important safety feature. A dedicated
battery enables you to start the generator regardless of the condition of the propulsion engine
batteries. If the batteries become discharged to the point where they are unable to start an
engine, start the generator, then turn on the engine battery chargers. When the engine batteries
are recharged to an adequate level, you can then start the propulsion engines.

To start the generator:
1. Read, understand and follow the OEM (Original Equipment
Manufacturer) information that describes the generator. The Start
switch is located on the upper left corner of the DC Panel.
2. The generator starter is powered by its own 12-volt battery. This
battery is located with the rest of the batteries. Power to the
generator from its battery is controlled by a master disconnect
switch located on the engine room bulkhead (see photo). Turn this
switch to the ON position.
A Tip From Marquis!
3. The generator engine uses a seawater cooling system. This system
includes a strainer that prevents debris in the seawater from
entering the cooling system's water pump. Close seacocks before
removing strainer. Remove and clean the strainer. The strainer
is located in the center of the engine room bilge area between the
Racor fuel filters.
4. Reinstall the strainer. If the strainer leaks when the seacock is
opened, close the seacock, then check the strainer for correct
installation.
