House (Aux.) Batteries
The house batteries supply current to 12-volt
equipment located in the living area of the motor
home. This includes interior lights, range exhaust
fan, furnace fan, water pump, water level and
holding tank gauges, 110-volt generator starter,
refrigerator and bath roof vent fan. The house
batteries may also be used to start the engine if
the chassis battery is dead. Refer to “Aux. Start
Switch.”
The house batteries are “deep-cycle” type
batteries specially designed for recreational
vehicle use. They will provide longer lasting
power than standard automotive batteries, and
will withstand the frequent drain-and-recharge
cycles that occur under the demanding conditions
of a camping outing.
The house batteries are automatically charged
by the engine alternator while the engine is
running.
BATTERY ACCESS
The batteries are located beneath the top
inside entrance step. Unhook the latch assembly
fastening the top step and remove.
AUXILIARY BATTERYSWITCH
(AUX. BATT)
The AUX BATT switch disconnects the
auxiliary (coach) batteries from the 12-volt
system of your coach to avoid long-term battery
drain by electrical items that are hooked directly
to the coach batteries, such as clock displays and
radio memories, etc.
Always leave this switch ON except during
storage periods. Some electronic displays and
memory functions may need to be reset after
power has been reconnected.
