ELECTRICAL SYSTEM
4.1
General
Your Pursuit is equipped with a 12-volt DC electrical system and 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.
4.2
12-Volt DC System
There are two batteries controlled by battery selector switches. One battery is reserved for engine starting.
The other battery serves house and electronics functions.
Distribution circuit breakers, located near the battery selector switches, protect the system from an overload.
Other circuit breakers, located near the selector switches, provide protection for the aft and forward bilge
pump, stereo and windlass. All 12-volt power is distributed to the 12-volt accessories through individual
circuit breakers on the main breaker panel. Most 12-volt accessories are operated directly by switches in the
helm, cabin and cockpit 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.
4.3
DC Distribution System
The battery switches are a part of an
integrated DC power distribution sys-
tem that contains several components.
The following are descriptions of the
components:
Battery Master Switch (2): These
switches feed the engine(s) and DC
circuits. These are "ON/OFF"
switches. Turn the switch so that the
green "ON" indicator is displayed.
Both switches should be in the "ON"
position whenever the boat is in opera-
tion.
