House Battery Bank & Switch
Two battery banks support 12-volt DC power: 1) engine battery; 2) house battery. (P XX)
The BATTERY SWITCHES are located in aft cabin over the engine compartment cover. Normally,
leave the GROUND SWITCH (far left switch as you face panel) in the On position.
The two (#1 & #2) 12 volt panels show all the systems supported by your batteries. Primarily you will be
turning on the breakers for your lights, water pressure, electronics, gas control valve, refrigeration, etc. (P
25). Interior lights are also powered from a circuit breaker on #1 panel but many have individual
switches at each fixture. The bilge pump is powered directly from the battery source and is not switched
at the panels. The bilge pump control switch is located next to the water heater in the settee locker across
from the navigation station. Your breakers such as gas valve (propane), shower and macerator pumps
should always be turned off after every use.
The HOUSE BATTERY BANK provides power for all DC systems. When disconnected from shore
power, all 12-volt devices and 110-volt devices drain the house battery. The house batteries are located
under the aft cabin berth (L 10).
Battery systems will lose their charge while ANCHORED or MOORED. Avoid this by using power
sparingly at anchor. Turn the refrigerator off at night. Use only one or two lights at a time. Turn off
systems not in use such as instruments, VHF, stereo, etc. If you stay moored for more than a day, run your
engines just above idle to recharge your batteries. It may take about 2 hours to significantly recharge
your batteries. WATCH YOUR VOLTAGE! The Link 10 system reports on the status and current drain
on your house batteries. Begin recharging when the batteries are reduced to 50% capacity. (Complete
Link-10 instructions are contained in the Equipment manual #2 stored in the forward cabin Port locker.)
Batteries are charged by the engine ALTERNATOR while underway. The engine/house batteries are
charged by the BATTERY CHARGER when connected to shore power.
There is one cigarette lighter type 12 volt auxiliary plug located next to the VHF radio at the navigation
station. It operates off battery power alone and is switched at Panel #2. It can be used to operate car
chargers, the second 1.1V TV/DVD inverter and Portable spotlight (stored underneath navigation station;
power cord runs to deck through an open forward galley Portal).
Note -- Do not change the position of the battery switches while the engine is running or the alternator
diodes will be damaged. Change position with the engine off.
