Chapter 4:
ELECTRICAL SYSTEM
4.1 General
Your Pursuit is equipped with a 12-volt DC electrical system and a 110-volt AC system. The AC
system draws current from shore power outlets at dockside. The DC system draws current from
two (2) on-board batteries.
The 12-volt batteries in your boat are normally 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 system. There are two (2) batteries, one for the starboard
engine and one for the port engine. The batteries are located below the bridge deck and can be
accessed through the hatch located between the helm and passenger seat. They are controlled by
two (2) battery selector switches. The batteries themselves can be charged by either engine
separately, both engines simultaneously, or by the battery charger when hooked to shore power.
All 12-volt power is distributed to the 12-volt accessories through individual circuit breakers
located in the 12-volt switch panels or the circuit breaker panel. A main circuit breaker, located
near the battery selector switches, protects the system from an overload. Other circuit breakers,
located near the selector switch, protect the circuit for the automatic float switch for the aft bilge
pump and the windlass. Most 12-volt accessories are operated directly by switches in the helm and
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.
