Your boat is equipped with a 12 volt DC (Direct Cur-
rent) 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 posi-
tioned to prevent abrasion and exposure to moisture, as
well as to remain accessible for inspection, repairs, and
the addition of aftermarket 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.
Your boat's 12 volt DC electrical service has been sepa-
rated into three battery banks:
1. Engines (two batteries - one for each engine)
2. House (two batteries)
3. Optional generator (one battery)
Power from each of the battery banks is regulated
though a dedicated master disconnect switch. Placing a
master disconnect switch in the "ON" position allows
the involved battery bank to supply power to its 12 volt
equipment. The batteries are arranged along the boat’s
centerline in the engine room, beneath a hatch between
the propulsion engines.
Each propulsion engine has its own dedicated battery.
To provide electricity to the engine starters, place the
engine master disconnect switches in the "ON" position.
These switches are located on the Safety Breaker Panel,
which is in the forward bulkhead of the aft stateroom,
next to the salon stairs.
The voltage levels of both engine batteries are moni-
tored and maintained through a single 60 amp battery
charger. With your boat connected to a source of AC
power, this battery charger automatically maintains the
voltage levels within the two engine batteries when
their voltage drops below a predetermined level. The
battery charger is located in the engine room on the port
aft bulkhead. Refer to the "Battery Charger 1" portion
of Section 3 for more information on operating this
battery charger.
