Class A
Check auxiliary generator oil level frequently
during periods of use. Refer to the generator
manufacturer’s information in your InfoCase for
specific recommendations.
ELECTRICAL SYSTEM – 12V
DC
The DC voltage system consists of the chassis
battery and the 12-volt house auxiliary batteries.

See “Power Center” in this Section.
Chassis (Starting) Battery
The chassis battery is used to operate the
engine starter and automotive accessories and
controls found on the instrument panel. The
leveling jack, slideout room systems and the
electric step are also connected to the chassis
battery.
The chassis battery is located in the engine
compartment. See your chassis owner’s manual
for instructions.
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 starting,
refrigerator and bath roof vent fan. The house
batteries may also be used to start the engine if
the chassis battery is discharged. Refer to Battery
Boost Switch in Section 3.
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.
AUXILIARY BATTERY (AUX
BATT) SWITCH
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 for
periods when the vehicle is not in use.
Some electronic displays and memory
functions may need to be reset after power has
been reconnected.
BATTERY ACCESS
The batteries are located beneath the top
inside entrance step.
WARNING
Never check generator oil level while
generator engine is running.
