ELECTRICAL SYSTEM
4.1 General
Your boat is equipped with a 12-volt D.C. electrical system that draws current from on-board
batteries.
The 12-volt batteries in your boat are usually the lead-acid type. They will require maintenance
similar to those found in automobiles. The batteries are located just forward of the fuel tank and
accessed through a door in the cabin below the companionway door. The battery switch and
primary circuit breakers are located in the transom area behind the starboard access hatch.
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 batteries controlled by one battery
switch. The batteries are charged by the engine. All 12-volt power is distributed to the 12-volt
accessories through individual circuit breakers located in the 12-volt switch panels. A main circuit
breaker located near the battery switch protects the system from an overload. Another circuit
breaker near the switch protects the circuit for the automatic float switch for the bilge pump. 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.
Single Engine Battery System
The battery selector switch is located in the transom area of the boat.
The switch feeds the engine and the 12-volt accessory panel. 12-
volt power can be supplied by either battery # 1 or battery # 2
separately or by both batteries simultaneously. The selector switch
also directs the charging current when the engine is operating.
For example: When the switch is on battery # 1, the engine and the
12-volt system will be supplied power by battery # 1. Battery # 2
will be isolated and in reserve. Battery # 1 will be charged by the
Battery Switch
