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 four areas, each powered by one
or more 12-volt batteries:
• Engines
• Bow and optional stern thrusters
• “House” systems
• Generator.
2.1.1 Engine Batteries
Each propulsion engine has its own battery. If your boat has Volvo D12
engines, there are two batteries for each engine. The engine batteries
are located in the engine room at the base of the aft bulkhead.
Electricity from each battery (or battery pair) to its engine is controlled
by a master disconnect switch. These switches are located in the engine
room on the aft bulkhead, just above their respective engine battery(ies).
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 batter-
ies and their master disconnect switches.
2.1.2 Bow and Stern Thruster Batteries
If your boat has Volvo D12 engines, the bow thruster is powered by the
port engine batteries; the optional stern thruster is powered by the
starboard engine batteries. If your boat does not have Volvo D12 engines,
the bow thruster is powered by the port engine battery and an additional
dedicated battery; the optional stern thruster is powered by the star-
board engine battery and an additional dedicated battery. The dedicated
thruster batteries are located in the engine room on the centerline.
