David Walters Shani II Operation Manual page 6

SHORE POWER supports all AC equipment and receptacles on board, as well as the battery chargers.
To connect to shore power, plug the 30 Amp POWER CORD into the boat and then into the dock receptacle.
Check the power rating/plug size of the nearest dock receptacle (that is 50 amp, 30 amp, 20 amp, or 15 amp).
If necessary, add a CORD ADAPTER located in the engine room on then port side. Turn the dock power
on. Cords coming off the bow can be wrapped loosely around the bow line.
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. Watch you 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.
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 in the engine room on port side, mounted to the forward
bulkhead. 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 engine room, port side. 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. Use these items VERY
SPARINGLY! Monitor your battery usage very carefully!
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 usually a circuit breakers located on
top of the inverter box.
House (12-volt) System
3 battery banks support 12-volt DC power: 1) engine battery 2) house battery bank
The BATTERY SWITCHES are located near floor at the lower helm. Normally, leave the ENGINE and
HOUSE SWITCHES in the 'ON' position. Note -- Do not change the position of the switches while the
engines are running or the alternator diodes will be damaged. Change positions with the engines off.
Your 12 volt panel shows all the systems supported by your batteries. Primarily you will be turning on the
breakers for your lights, water pressure, electronics, etc. Bilge pumps should always be left on.
Your breakers such as propane and cabin heater should always be turned off after every use.
House Battery Bank & Switch
The HOUSE BATTERY BANK provides power for all DC systems, except the engines and the automatic
bilge pumps. When disconnected from shore power, all 12-volt devices drain the house battery. Use
