ELECTRICAL
Chassis Battery
The chassis battery is used to operate the
engine starter and automotive accessories and
controls found on the instrument panel. The
electric step is also connected to the chassis
battery.
Refer to your chassis manual provided in your
InfoCase 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
motorhome. 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,
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” in
Section 3 - Driving Your Motorhome
).
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 motorhome 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 connected while
using the motorhome.
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/coach batteries (and chassis
batteries in certain models) are located beneath
the interior entrance steps. With the Residential
Refrigerator, the house batteries are accessed by
a separate exterior door.
