6.1 General
Your boat is equipped with a 12 volt DC electrical
system and a 120 volt AC battery charging system.
The battery charger draws current from a shore
power outlet at dockside. The DC system draws
current from onboard batteries.
Your boat and engine charging system is designed
for 12 volt marine batteries. All wires in the elec-
trical systems are color coded to make identifying
circuits easier.
6.2 DC System Overview
The 12 volt system is a fairly standard marine sys-
tem. Your boat is equipped with 4 batteries, one for
each engine and two for the house and electronics.
The engine and the house batteries are located in
the battery compartment below the helm seats. If
your boat is equipped with an optional Seakeeper
and/or freezer plate, a 5th battery will be added
to the system.
The engine and house battery systems are con-
trolled by three battery switches, two for the
engines and one for the house 12 volt accessories
and electronics. The batteries are charged by the
engines or the battery charger when connected to
shore power.
Most 12 volt power is distributed to 12 volt acces-
sories through individual circuit breakers and fuses
located on the fuse and breaker panel in the bat-
tery compartment. There are also fuse panels for
electronics and other accessories behind the access
door in the aft head compartment bulkhead and
behind the hardtop electronics panel. All circuit
breakers or fuses are labeled with the name of the
circuit they protect.
Main circuit breakers near the battery switches
in the fuse and breaker panel in the battery
compartment protect the primary circuits for the
digital switching system, stereo amplier, windlass,
hardtop, trim tabs, windshield hydraulic circuits,
optional Seakeeper, and other circuits. Additional
main circuit breakers in the aft systems compart-
ment protect the house circuits in the aft bilge.
Other fuses in panels located on the fuse and
breaker panel protect continuous power circuits for
the stereo memory, automatic switches for bilge
pumps and high water alarm, selected 12 volt ac-
cessories and the remote battery switches.
Most 12 volt accessories are operated by switches
in the helm switch panels, head compartment or
digital switches in the Garmin displays. Most ac-
cessory circuits are protected by circuit breakers
in the digital switch control modules or fuses in
the accessory fuse panels.
Main breakers or fuses located on each engine
protect the ignition systems and the gauge panel
display. Other main, heavy duty fuses or circuit
breakers in the aft systems compartment protect
the primary engine control circuits.
Most outboard engine electrical circuits are pro-
tected by fuses located in a fuse panel on the
side of the engine. Some engine fuse panels are
equipped with a spare fuse for each circuit. Always
replace fuses with the fuse specied by the engine
manufacturer. Refer to the engine owner’s manual
for more information on the fuses, fuse panels or
circuit breakers on your engines.
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.
