ELECTRICAL SYSTEM
4.1 General
Your Pursuit is equipped with 12-volt DC and AC electrical systems. The AC system draws
current from shore power outlets at dockside. The DC system draws current from three on board
batteries.
The 12-volt batteries in your boat are of the lead-acid type. They will require similar
maintenance as those found in automobiles. (DO NOT USE GEL- CELL BATTERIES.)
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 standard marine system. There are three batteries located in a
compartment in the leaning post. There is 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. 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 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 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.
All 12-volt power is distributed to the 12-volt accessories through individual circuit breakers
located in 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 switches
for the aft and forward bilge pumps. 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 and
accessory switch panels.
