ELECTRICAL SYSTEMS
The coach battery supplies current to 12-volt
equipment located in the living area of the motor
home. This includes: interior lights, refrigerator,
furnace fan, water pump, water level and holding
tank gauges, and 110-volt generator starter.
The coach battery is automatically charged by
the engine alternator while the engine is running.
12-VOLT FUSES AND CIRCUIT
BREAKERS
All 12-volt circuits and equipment in the
coach area of the motor home are protected by a
fuse or circuit breaker panel. When a circuit is
overloaded or a short develops in any part of the
system, a fuse or breaker will shut down that cir-
cuit. If this happens, turn off all affected lights or
appliances and reset the breaker or replace the
fuse with a new one of equal amperage rating.
Modified Reset Circuit Breaker
A modified reset breaker is located in the bat-
tery compartment. This type of breaker cannot be
manually reset. It must have the electrical current
disconnected in order to reset itself. This means
turning off or unplugging all electrical devices
then disconnecting the coach battery cable for a
few seconds until the breaker resets. If the break-
er keeps tripping, an electrical malfunction exists
somewhere in the coach and requires service
from your dealer.
FUSE PANEL
The fuse panel is mounted on the right-hand
side of the load center.
A label on the panel states the amperage rating
and circuit protected for each fuse.
12-Volt Breaker Panel - Model 22FD
12-Volt Fuse Panel - Model 22QD & 22HD
The fuse panel accepts only blade type plug-in
fuses. Always replace fuses with those of the
same amperage rating.
