2.0 DC Electrical System
Your boat is equipped with a 12-volt DC (Direct Current) electrical
system. This is a comprehensive system that is designed to meet your
present and future 12-volt electrical needs. Wire-runs and connections
are positioned to prevent abrasion and exposure to moisture, as well as
to remain accessible for inspection, repairs, and the addition of aftermar-
ket electrical accessories.
Wires used throughout the DC electrical system are plastic-coated and
color-coded. Connections are made using crimped connector points. The
electrical system is virtually maintenance free, with only the batteries
requiring periodic inspection and maintenance.
2.1 Batteries
The DC electrical system is divided into three areas, each powered by
one or more 12-volt batteries:
• Engines (two batteries - one for each engine)
• “House” (one battery)
• Generator (one battery).
2.1.1 Engine Batteries
Each propulsion engine has its own dedicated battery. These batteries
are located in the engine room beneath the centerline catwalk. The
engine batteries are the two middle batteries.
Electricity from each battery to its engine is controlled by a master
disconnect switch. These switches are located in the engine room on the
forward bulkhead. To provide electricity to the engines, turn the master
disconnect switches to the “ON” position.
Refer to 9.7.4 Engine Room for the exact location of the engine batteries
and their master disconnect switches.
2.1.2 “House” Battery
The equipment controlled by the three DC circuit breaker panels (Safety
Breaker Panel, DC Control Center and Bridge Breaker Panel) is pow-
ered by a single battery. This battery is located in the engine room be-
neath the centerline catwalk, forward of the engine batteries.
Electricity from the battery to the boat’s various DC circuit breaker
panels is controlled by a master disconnect switch. This switch is located
on the Safety Breaker Panel, which is located in a cabinet in the inboard
end of the galley counter. To provide electricity to these breaker panels,
turn the master disconnect switch to the “ON” position.
