BOATS
Electrical System
the generator or shore power circuit if too many
AC accessory breakers are activated. Too much
amperage being supplied through the panel will
cause the Shore Main or Generator breaker to trip
and could damage the system. This is particularly
important when operating the air conditioner and
water heater. You should always be aware of the
electrical load needed to activate accessories and
manage the amperage being supplied so the load
can be kept within safe limits. If you have any
questions about managing the power in your boat,
contact your Monterey dealer.
Reversed Polarity Lights
The red LED light indicates reverse polarity current
supplied to the panel. This situation will cause
the red light to remain lit. If reverse polarity is
achieved, immediately turn off all cabin AC break-
ers and the dockside outlet breaker. Disconnect
the power cable from the dockside outlet and
dockside wiring.
Reverse Polarity Light Test Switch
There is a momentary switch located next to the
reverse polarity light in the AC breaker panel. This
switch is used to test the reverse polarity light to
ensure that they are functioning. The light can
be tested by depressing the switch whenever
the AC system is activated. The reverse polarity
light should be tested each time the AC system is
activated. If the light does not illuminate when
the switch is pressed, disconnect the shore power
light and the dockside wiring if necessary.
AC Panel Accessory Breakers
Outlets
Supplies 120 volt AC electrical current to
the cabin ground fault interrupter (G.F.I.)
electrical outlets.
NOTICE:
All AC electrical outlets are provided with
ground fault interrupts to protect against
electric shock. These outlets should be test-
ed periodically to ensure proper operation by
pressing the test/reset buttons in the center
of faceplate. G.F.I. outlets do not protect
against short circuits and overloads. This is
done by the outlet breakers on the AC panel.
G.F.I. OUTLETS DO NOT PROVIDE 100% PROTECTION
FROM ELECTRIC SHOCK. EVEN THOUGH GROUND FAULT
INTERRUPTERS PROVIDE PROTECTION BY REDUCING
EXPOSURE TIME FROM LINE TO GROUND SHOCK HAZARDS,
IT IS STILL POSSIBLE TO RECEIVE AN ELECTRIC SHOCK FROM
DEFECTIVE APPLIANCES OR POWER TOOLS AND MISUSED
ELECTRICAL EQUIPMENT.
Water Heater
Supplies electrical current directly to the hot water
heater circuit. A thermostat in the water heater
control panel automatically controls the water
temperature. Before operation, you must have
water in the water heater. (See the water heater
manual for details)
Battery Charger
Supplies electrical current directly to the automat-
ic battery charger. The battery charger recharges
and maintains the 12-volt batteries simultane-
ously when activated. It is fully automatic. See
the battery charger manual for more information.
The charge to the engine batteries can be moni-
tored by using the volt meters in the engine gauge
cluster. To monitor the engine batteries, activate
the charger and turn the engine battery switches
on. Turn the ignition key switch for each engine
to the “ON” position (DO NOT START THE EN-
GINES) and read the voltage on the volt meter
for each engine. To monitor the house battery,
activate the charger and turn the HOUSE battery
switch ON. Read the volt meter in the cabin DC
breaker panel. If the batteries are in good con-
dition and charging properly, the volt meters will
indicate between 12 and 14.5 volts. If the reading
is below 12 volts, then the battery is not accepting
a charge or the charger is not working properly.
Always turn the ignition switches off immediately
after the monitoring is complete. Refer to the
battery charger manual for more information.
The wires that supply DC charging current to the
batteries are protected by an internal fuse in the
battery charger and 3 external breakers, one for
each battery output wire, located in the engine
compartment breaker panel near the battery
switches. The external breakers protect the DC
charging circuit from the batteries to the charger.
The internal fuses in the charger protect the DC
charging circuit from the charger to the batteries.
