5. Turn on the “AC Main” circuit breaker and any of the
circuit breakers for the 110 volt AC systems desired.
The shore power cords coming off the bow can be wrapped
loosely around the bowline.
On shore power, the electrical outlets will be functional under the
110 volt AC system.
They will not work under the 12-volt DC system.
12 Volt DC System
This system is powered by the marine batteries aboard
Andiamo
,
and powers everything onboard not powered by the 110 volt AC
system. The House battery is Battery #2 and is located in front of
the engine under the companionway stairs. The engine start battery is Battery #1 and is in the engine
compartment just aft of the engine. Make sure “BOTH” batteries are ON when under power, or when
connected to shore power for recharging. When at anchor and/or not on shore power turn Battery #1 off.
This way even if the House battery is low you will still have power to start the engine.
Note -- Do not change the position of the battery switches while the engine is running, or the alternator
diodes will be damaged. Change positions with the engine off.
The running, steaming, and anchor lights are all controlled from the electrical panel above the navigation
table. Interior lights are also powered from a circuit breaker on this panel. Each interior light also has an
individual switch at each fixture.
There are two 12 volt auxiliary plugs (cigarette lighter plugs). One located on the electrical panel, and the
other on the binnacle in the cockpit.
When not connected to shore power, the house battery is providing all power. Avoid draining the batteries
by using power sparingly at anchor:
1. Turn the refrigerator off at night, as it will still stay cold.
2. Use only one or two lights at a time.
3. Turn off systems not in use such as instruments, VHF, autopilot, running lights, steaming
lights, tank indicators, stereo, etc.
If you do not need the diesel forced air heater, it may be turned off as well. Monitor the use of onboard
electricity carefully with your voltmeter located at the navigation station.

Troubleshooting Electrical Systems
1. Battery running low
. Signs of this are lights dimming, stereo not working. Immediately start engine and
run for a period of time at 1600 RPM with both battery switches “ON”.
2. Unable to start the engine due to low battery
. Retry. If engine starts, recharge as above. If it does not
work, see engine troubleshooting or contact AYC for instructions.
