ELECTRICAL SYSTEMS
4-3 53 COUPE
When the boat is using its generator or
a shore power connection, the 120V AC
battery charger may be used. To oper -
ate the AC battery charger, switch ON
the three BATTERY CHARGER breakers
on the Master DC Panel on the forward
engine room bulkhead ( Figure 4-1 ), and
the BATTERY CHARGER breaker on the
AC Distribution Panel located beneath the
starboard salon loveseat (
Figure 4-2
).
It is important that your batteries be kept in
a state of full charge as much as possible.
Fully charged 12V batteries will indicate a
voltage in excess of 12.6 volts with no load,
or while being charged.
Prolonged periods of discharge will cause
the batteries to deteriorate rapidly, and will
result in their inability to hold a charge for
the expected amount of time. This can hap -
pen easily if excessive DC loads (such as
lights) are left on while the battery charger
is off.
Always leave your boat connected to
shore power with the battery charger
ON when leaving for any extended pe -
riod of time.
4.1.3 Distribution
Power from the battery banks supplies the
red main battery switches at the bottom of
the Master DC Panel ( Figure 4-1 ), located
on the forward engine room bulkhead.
Power from each engine bank is connected
to its respective engine battery bank switch, and power from the house bank
is connected to the house battery bank switch. The red main battery switches
are controlled remotely by the PORT BATTERY, HOUSE BATTERY, and STBD
BATTERY buttons on the Power Control Panel in the galley peninsula cabinet.
