Electrical System
Alternating Current
Shore power is used for the operation of A/C devices like your air conditioner, battery
charger, and 110v outlets for other appliances. Turn off the main A/C breaker switch
prior to plugging into shore power to minimize contact arcing. The panel is located in the
cabin. If the reverse polarity light is on, unplug shore power and do not use it until this
potentially dangerous situation is corrected by a qualified technician. The battery charger
switch should be on to keep batteries fully charged.

Direct Current
12 volt direct current provides electrical power for all lighting, pumps, electronics, and
D/C devices. A main breaker panel is located in the bilge on the bulkhead. Additional
D/C switches and breakers are located on the cabin and dash panels. There is also a D/C
terminal bus panel located behind the helm. Battery selector switches are for battery
isolation, parallel operation, and disconnect. Caution: To avoid possible alternator /
battery damage on twin engine installations, insure the dual battery switches are never
left so both engines are connected together (never leave a switch on "BOTH" or "ALL").
The preferred switch position is port engine to port battery, starboard to starboard.
