ELECTRICAL SYSTEM
4.1 General
Your Pursuit is equipped with AC and 12-volt DC electrical systems. The AC system can draw current from
one of two sources, either shore power outlets at dockside or the optional generator. The DC system draws
current from on-board batteries.
The Group 31, 12-volt batteries provided in your boat are of the lead-acid type. They will require periodic
maintenance. The batteries are located in compartments under the port and starboard cockpit steps. The engine
batteries are located on the starboard side; the house and the electronics are located on the port side.
There are electrical schematics included in this manual to assist with servicing the electrical systems.
4.2 12-Volt DC System
The 12-volt system is a standard marine system.
There are four batteries, one for starting each
engine, a house battery and a separate battery for
electronics. All batteries can be charged by the
engine or by the battery charger when connected to
shore power. An automatic voltage control system
manages charging of the batteries whenever the
engine is running. The battery condition can be
monitored by a DC voltmeter switch panel located
on the cabin DC breaker.
Twelve-volt power is distributed to the 12-volt accessories through individual circuit breakers on the helm
and cabin circuit breaker panels. Main breakers located on the battery switch panel protect these panels. Other
circuit breakers on the module protect the circuits for the optional windlass, high amperage components, the
stereo memory and the automatic float switches for the aft and mid bilge pumps. A circuit breaker located
on each engine protects the engine ignition systems and gauges.
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.
