ELECTRICAL SYSTEM
4.1 General
Your Pursuit is equipped with a 12-volt DC electrical system and may be equipped with an optional AC system.
The AC system draws current from shore power outlets at dockside. 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.
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 three batteries located in a compartment aft of the
V-berth, below the cabin door. There is one battery for the starboard engine, one battery 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. An automatic 12-volt current control system called the “Total
Automatic Battery System
®
(TABS) manages the charging current for the 12-volt system whenever the
engines are running. The TABS 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 the 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 TABS indicates that the parallel switch is activated. Please refer to the TABS
owner's manual for additional information on the operation and maintenance of this system.
Most 12-volt power is distributed to the 12-volt accessories through individual circuit breakers located on the
helm or on the 12-volt breaker panel in the head compartment. A main breaker located on the front of the
TABS protects the DC system from an overload. Other circuit breakers, located on the front of the TABS,
protect the circuit for the optional windlass, and the automatic float switch for the bilge pump. The engine
main breakers or fuses located on each engine protects the ignition systems and gauges. Some 12-volt
accessories are operated directly by a circuit breaker in the breaker panel while others are operated by a switch
fed by the breakers. Most of the 12-volt accessories on the deck and cockpit are operated by switches in the
helm or 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.
