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 on-board batteries.
Pursuit electrical systems are designed to use lead-acid type batteries. Your boat has provision
for two batteries. These batteries should be of the size and capacity recommended by the
manufacturer of your engine. See the engine owner's manual. These specifications should be
considered to be the minimum size battery required.
There are electrical schematics included in this manual to aid in following an individual circuit
of the boat.
4.2 12-volt DC System
The 12-volt system is a fairly standard marine system. There are two batteries, one for starting
the engine and a house or accessory battery. The batteries themselves can be charged by the
engine or by the battery charger when hooked to shore power. An automatic voltage control
system manages the charging voltage for the 12-volt system whenever the engine is running. The
system is equipped with a battery parallel feature that allows both batteries to be connected in
parallel for extra battery power while starting the engines. The battery parallel switch is a manual
switch located in the battery switch panel that is labeled “Emerg Parallel.” Please refer to the
control system 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 in
the 12-volt breaker panel located in the equipment compartment aft of the cabin. A main breaker
located on the control module protects the system from an overload. Other circuit breakers on
the module protect the circuit for the optional windlass, the main DC power, the stereo memory
and the automatic float switches for the aft and mid bilge pumps.
A circuit breaker located on the engine protects the ignition systems and gauges. Some 12-volt
accessories are operated directly by a circuit breaker in the 12-volt breaker panel while others
are operated by a switch fed by the panel breakers. Most of the 12-volt accessories on the deck
and cockpit are operated by switches in the helm and accessory switch panels.
