To connect to shore power, plug the 30 amp cord into the dock receptacle. Check the power rating/plug
size of the nearest dock receptacle (that is 30 amps, 20 amps, or 15 amps). If necessary, add a CORD
ADAPTER located in the small outside fold down locker forward of the freezer. Turn the dock power
on. At the ELECTRICAL PANEL, flip the SHORE CIRCUIT BREAKER on. Check for reverse
polarity. Then turn on appropriate breakers for battery charger, refrigeration, water heater, and
microwave, etc. Watch your volt meter for load. If the load exceeds voltage, you will pop your breaker.
If this occurs, wait to turn on one of your systems (i.e. water heater) until your use of volts drop.
If your outlets fail to work, check your GFIs to make sure that they have not been tripped.
When disconnecting from shore power, turn off the dock receptacle before disengaging the power
cord. Leave the power cord connected to the boat at 30 Amp receptacles.

Inverter Power

The INVERTER provides AC power to the 110-volt receptacle plugs (i.e. the microwave oven) when the
boat is disconnected from shore power. The inverter does not provide power to the water heater or the
battery charger. Your inverter panel is located at the helm station with an on/off switch. Make certain
that it is on. The actual inverter is located in the engine room.
The inverter's power source is the DC house or inverter batteries located in the engine room. The
quantity of DC power is limited to the capacity of these batteries. Therefore, running hair dryers,
toaster, coffeepots, space heater, etc. and will quickly discharge the house/inverter batteries. It is best if
you need to run the big appliance that you turn on the generator.
When connected to shore power, the inverter automatically becomes a battery charger for the 12-volt
HOUSE BATTERIES. Should you detect the inverter failing to charge the house batteries, check the
circuit breaker in the AC Panel. And the inverter control panel. Also, there is a circuit breaker located
on top of the inverter box.

Generator

To start the GENERATOR, first check that your generator's fluids are topped off and the raw water
intake is open. The generator controls are located at the lower helm. First pre-heat the generator by
pushing the top switch down for about 20 seconds. Then while still pre-heating lift the start switch. Hold
both switches in that position while the generator catches (about 5-10 seconds). Make sure water and
exhaust is exiting the port side stern.
After generator is running, change your AC distribution switch to generator. Then turn on AC systems
as you would on shore power one system at a time.
To turn the generator off, first take off the load by turning off AC breakers. Then turn off main AC
distribution switch. Let the generator run without a load for about 2-3 minutes to cool down. Lastly kill
the generator by switching generator switch to "off" until it dies.
