SECTION 6
ELECTRICAL
Refer to the generator manufacturer's
maintenance information in your InfoCase for
specific recommendations.
WARNING
Never check generator oil level while
generator engine is running.
12-VOLT DC SYSTEM
The DC voltage system consists of the chassis
battery, the 12-volt house batteries, and the 12-
volt power converter.
Converter
See "Power Center."
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
The house batteries supply power 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, 120-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.
(See "Battery Boost Switch" or "Aux Start
Switch.")
House batteries are "deep-cycle" type
batteries specially designed for recreational
vehicle use. They will provide longer lasting
power than standard automotive batteries, and
6-6
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 chassis alternator while the engine is
running.
AUXILIARY BATTERY
DISCONNECT SWITCH
(AUX. BATT)
The AUX BATT 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.
Aux. Batt. Switch - typical
(Near entrance door)
HOUSE 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.
