ELECTRICAL SYSTEM
4.1 General
Your Pursuit is equipped with 110-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 optional
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.
There are electrical schematics included in this manual to aid in following an individual circuit of
the boat.
4.2 12-Volt System
The 12-volt system is a fairly standard marine system. There are three batteries, one for the starboard
engine, one for the port engine and a house or accessory battery. 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 12-volt current control system called the Power Plant
®
manages the charging current for the 12-volt system whenever the engines are running. The power
plant automatically senses the condition of each battery and directs the available current to the
batteries that require charging. The system is equipped with a battery parallel feature that will
connect all three batteries in parallel for extra battery power while starting the engines. The battery
parallel switch is a momentary switch located in the helm switch panel that is labeled either
“Accessory” or “Parallel.” A red LED light on the front of the Power Plant indicates that the parallel
switch is activated. Please refer to the Power Plant owner's manual for additional information on
the operation and maintenance of this system.
All 12-volt power is distributed to the 12-volt accessories through individual circuit breakers
located in the 12-volt breaker panel in the cabin. A main breaker located on the front of the Power
Plant protects the system from an overload. Other circuit breakers, located on the front of the Power
Plant, protect the circuit for the optional windlass, the main DC power and the automatic float
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 cockpit are operated by switches in the helm and
accessory switch panels.
