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 aftermarket electrical accesso-
ries.
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 four areas, each powered by one or
more 12-volt batteries:
1. Engines (two batteries - one for each engine)
2. “House” (one battery)
3. Generator (one battery)
4. Bow thruster (four batteries).
2.1.1 Engine Batteries
Each propulsion engine has its own dedicated battery. These batteries are
located in the engine room at the base of the aft bulkhead, just aft of their
respective engine. The port engine battery is nearest the centerline; the
starboard engine battery is outboard.
Electricity from each battery to its engine is controlled by a master discon-
nect switch. These switches are located in the engine room on the aft bulk-
head, just above their respective engine battery. To provide electricity to
the engines, turn the master disconnect switches to the “ON” position.
Refer to the “Engine Room” portion of Section 9 for the exact location of
the engine batteries and their master disconnect switches.
2.1.2 “House” Battery
The “house” equipment controlled by the three DC circuit breaker panels
(Safety Breaker Panel, DC Control Center and Bridge Breaker Panel) is
powered by a dedicated battery. This battery is located in the engine room
at the base of the starboard aft bulkhead, nearest the centerline.
Electricity from the battery to the Safety Breaker Panel is controlled by a
master disconnect switch. This switch is located in the engine room on the
starboard aft bulkhead. To provide electricity to these breaker panels, turn
