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. Three batteries are located in the aft cockpit machinery space. The fourth battery is located
in the cockpit island.
There are electrical schematics included in this manual to assist with servicing the electrical systems.
COMPARTMENTS ON A PURSUIT BOAT MAY BE LIGHTED FOR NIGHT USE. LIGHT
BULBS GENERATE HEAT AND CAN IGNITE ORDINARY COMBUSTIBLES CAUSING A
FIRE. DO NOT PLACE OR STORE COMBUSTIBLE MATERIALS IN CONTACT WITH
LIGHT BULBS. TURN OFF ALL LIGHTING PRIOR TO LEAVING THE BOAT.
4.2 12-Volt DC System
There are four batteries, one for starting each engine, a house battery and two making up the house battery
bank. 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 DC voltmeters located on the cabin DC breaker panel.
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 panel protect the circuits for the optional windlass, high amperage components, the
stereo memory and the automatic float switches for the aft bilge pumps and forward sump pump. Circuit
protection is located on each engine to protect 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.
4.3 DC Distribution System
The battery switches are part of an integrated DC power distribution system that contains several components.
This panel is made up of battery switches, a voltage sensitive relay (VSR) and the 12-volt power distribution
breakers. Access to the battery switch panel is through a hatch located on the forward side of the cockpit island.
