ELECTRICAL SYSTEM

4.1 General

Your Albemarle is equipped with 240/120-volt AC and 12-volt
DC electrical systems. The AC system can draw current from
one of two sources, either shore power outlets at dock side or
the generator. The DC system draws current from on board
batteries.

The 12-volt batteries in your boat are usually the lead-acid
type. They will require similar maintenance as those found
in automobiles.

4.2 12-Volt System

The  12-volt  system  is  a  standard  marine  system. There  are
three, two battery banks, one for the starboard engine, one for
the port engine and one for the house circuits.   The batteries
themselves can be charged by the engines or by the battery
charger when hooked to shore power or when operating the
optional generator.  An automatic battery isolator manages the
charging current for the 12-volt system whenever the engines
are running.  The isolator automatically senses the condition
of each battery bank and directs the available current to the
batteries that require charging.  The system is equipped with a
battery parallel feature that will connect both engine starting
battery banks in parallel for extra battery power while start-
ing the engines.  The battery parallel switch is activated by a
momentary rocker switch located in the helm switch panel.
When the switch is pressed, a relay is engaged that connects
both engine starting battery banks, when the switch is released,
the relay is deactivated and the battery banks are isolated.

Most 12-volt power is distributed to the 12-volt accessories
through  individual  circuit  breakers  located  in  the  12-volt
breaker panel in the cabin.  Main breakers located near the
house  battery  switch  protects  the  system  from  an  overload.
Other circuit breakers, located in the battery switch panel, pro-
tect the circuit for the optional windlass, the main DC power,
the engine hatch and the automatic switches for the aft and
forward bilge pumps.   The engine main breakers located on
each engine protects the ignition systems and gauges.  Some
12-volt accessories are operated directly by a circuit breaker in
the cabin breaker panel while others are operated by a switch
fed by the panel breakers.  Most of the 12-volt accessories on
the deck and in the cockpit are operated by switches in the
helm and accessory switch panels.

PROPER FUSE OR BREAKER PROTECTION MUST
BE  PROVIDED  FOR  ALL  12-VOLT  EQUIPMENT
ADDED.    DO  NOT  OVERLOAD THE  ACCESSORY
CIRCUIT  BREAKERS  OR  OTHER  CIRCUITRY
THROUGH ADDITIONAL 12-VOLT EQUIPMENT.

Battery Switches

There are three  “ON” - “OFF”  battery switches located on the
battery switch panel in the equipment compartment below the
cabin.  The port battery switch activates the port engine, the
starboard battery switch activates the starboard engine and the
third battery switch, on a separate panel activates the 12-volt
breaker panel in the cabin and all other 12-volt accessories.
Make sure that all three switches are activated whenever the
engines are running to ensure that all 12-volt accessories will
operate when they are needed.
