main distribution panel.

Battery Maintenance
• Check the fluid level in the cells approximately
every four (4) weeks, and more often in summer
and in hot zones.
• The fluid level must be between the lower and
the upper markings.
• Do not use metal funnels. Only replenish with
distilled water.
• Keep the battery clean and dry. Coat the battery
terminal clamps with silicone grease.
• Only use a battery charger designed to charge
automotive/marine type batteries when the bat-
teries are disconnected from the boat’s electrical
circuit.
MAIN BATTERY SWITCHES AND
SOLENOIDS
On the salon DC distribution panel (Figure 7.2) the
battery switches control the battery solenoids, which
are located in the Main Disconnect enclosure on the
aft bilge component board.
When the switches are in the OFF position, all 12
volt current to the engines and accessories is turned
off except for power to the bilge pumps and other
line side circuits (i.e., stereo memory, systems mon-
itor, blowers, etc.). The battery solenoids must be in
the ON position to start the engines or generator.
Turn the battery solenoids OFF when leaving the
boat for extended period of time.
NOTE: The bilge pumps, emergency bilge
pumps, cable master, sump pump, stereo mem-
ory, and carbon monoxide monitor CANNOT be
turned OFF with the battery solenoid. The entire
remaining DC system CAN be turned OFF with
the battery solenoid.
Main Battery Solenoids
The main engine and generator solenoids are locat-
ed inside the Main Disconnect Enclosure, which is
located on the aft engine room component board
(Figure 7.3).
