Chassis Battery
The chassis battery is used to operate the
engine starter and automotive accessories and
controls found on the instrument panel. The
slideout room systems and the electric step are
also connected to the chassis battery.
See your chassis manual for further
information on chassis batteries and chassis
electrical system.
House Batteries
House batteries are “deep-cycle” type
batteries specially designed for recreational
vehicle use. They will provide longer lasting
power than standard automotive starting batteries
and will withstand the frequent drain-and-
recharge cycles that occur under the demanding
conditions of a camping outing.
The house batteries supply power to 12-volt
equipment located in the living area of the motor
home. This includes the following 12-volt
powered components (if equipped): interior 12-
volt lighting, range exhaust fan, propane furnace
fan, fresh water pump, systems monitor panel
with water level and holding tank gauges,
refrigerator, roof vent fans, and 120-volt
electrical generator starter.
The house batteries can also provide
emergency power to start the engine if the chassis
battery is discharged. (See “Battery Boost
Switch” or “Aux Start Switch”).
House batteries are automatically charged by
the chassis alternator while the engine is running.
HOUSE/COACH BATTERY
DISCONNECT SWITCH
(COACH BATT)
The House/Coach Battery Disconnect switch
lets you disconnect the house batteries from the
12-volt system of your coach during storage
periods to avoid battery drain by electrical items
that are hooked directly to the house batteries,
such as clock displays and radio memories, etc.
Always leave this switch ON while using the
coach.
NOTE: Some electronic displays and memory
functions may need to be reset after
power has been reconnected.
See also “Battery Care” elsewhere in this
section.
BATTERY ACCESS
The house batteries are located in a
compartment beneath the interior entrance steps.
Unfasten the step retainer, then lift the step
upward and remove to service batteries.
