ELECTRICAL SYSTEMS
Check auxiliary generator oil level frequently
during periods of use. Refer to the generator
manufacturer’s information in your InfoCase for
specific recommendations.
The generator compartment is on the rear right
side of the vehicle. A prop rod holds the door
open while servicing. Insert the end of the prop
rod into the hole provided in the door frame as
shown.
12-VOLT DC SYSTEM
The DC voltage system consists of the chassis
battery and the 12-volt motor home auxiliary
(house) battery.
Automotive (Starting) Battery
The chassis battery is used solely to operate
the engine starter and all automotive accessories
and controls found on the instrument panel. This
includes the horn, speed control, all exterior
lights, radio, windshield wipers, etc.
House Battery
The house battery supplies current to all 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 the bath roof vent fan.
The house battery may also be used to start the
engine if the chassis battery is dead. Refer to
“Aux. Start Switch.”
The house battery is a “deep-cycle” type bat-
tery specially designed for recreational vehicle
use. It 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 battery is automatically charged by
the engine alternator while the engine is running.
12-Volt House Fuses and Circuit
Breakers
All 12-volt circuits and equipment in the
coach area of the motor home are protected by ei-
ther a fuse panel or breaker panel. When a circuit
is overloaded or a short develops in any part of
the system, a fuse or breaker will shut down that
circuit. If this happens, turn off all affected lights
or appliances and reset the breaker or replace the
fuse with a new one of equal amperage rating.
A label on the panel states the amperage rating
and circuit protected for each fuse or breaker.
Fuse Panel
The fuse panel is mounted on the right-hand
side of the power converter.
Never check generator oil level while
generator engine is running.
