______________________________ 25
The electrical systems in your motor home are designed
and built in accordance with all regulations, codes, and
standards in effect at the time the motor home was built.
CHASSIS ELECTRICAL SYSTEM
This is the vehicle electrical system. It includes the
vehicle battery, charging system, ignition system, instru-
ment panel and controls, and the headlights, taillights,
turn signals, and o\her vehicle lights and accessories.
Chassis Bulbs And Fuses
Replace bulbs with equivalent types as marked on the
bulb.
Fuses for the chassis electrical system are located under
the instrumeni panel. Additional fuses may be located
underthe hood. Others may be found in the 12-volt power
leads on the related equipment and accessories.
12-VOLT COACH SYSTEM
All 12-volt lighting fixtures, convenience outlets, 12-volt
powered vents, fresh water pump, and 12-volt accesso-
ries are included in this system.
The 12-volt power is provided by special deep-cycle, high
capacity coach storage battery/ies. Power is also pro-
vided by an AC/DC power converter for use when the
motor home is plugged into a 120-volt power source.
Battery charge is maintained by the motor home engine
alternator, or by the converter.
NOTE: All living area radios and tape decks draw
from the chassis or coach battery, and extended
usage when not traveling may discharge them.
WARNING
DO NOT USE THE MOTOR HOMEWHEN THE
COACH BATTERY IS DISCONNECTED. THE
POWER STEP WILL NOT OPERATE AS DE-
SIGNED IF THE COACH BATTERY IS DIS-
CONNECTED.
Battery Inspection And Care
WARNING
DISCONNECT THE 120-VOLT ELECTRIC
CORDANDTHE NEGATIVE TERMINAL FROM
THE COACH BATTERYIIES BEFORE WORK-
ING ON EITHER ELECTRICAL SYSTEM.

SYSTEMS
WARNING
REMOVE RINGS, METAL WATCHBANDS,
AND OTHER METAL JEWELRY BEFORE
WORKING AROUND A BATTERY. USE CAU-
TION WHEN USING METAL TOOLS. IF A TOOL
CONTACTS A BATTERY TERMINAL OR
METAL CONNECTED TO IT, A SHORT CIR-
CUlT COULD OCCUR WHICH COULD CAUSE
PERSONAL INJURY OR FIRE.
WARNING
DO NOT ALLOW BATTERY ELECTROLYTE
TO CONTACT SKIN, EYES, FABRICS, OR
PAINTED SURFACES. THE ELECTROLYTE IS
A SULFURIC ACID SOLUTION WHICH COULD
CAUSE SERIOUS PERSONAL INJURY OR
PROPERTY DAMAGE. WEAR EYE PROTEC-
TION WHEN WORKING WITH BATTERIES.
Check the external condition of the battery periodically.
Look for cracks in the cover and case. Check the vent
plugs and replace if they are cracked or broken. Keep the
battery clean. Accumulations of acid film and dirt may
permit current to flow between the terminals and dis-
charge the battery.
To clean the battery, wash it with a diluted solution of
baking soda and water to neutralize any acid present,
then flush with clean water. Foaming around terminals or
on top of the battery is normal acid neutralization. Avoid
getting the soda solution in the battery. Be sure the vent
caps are tight. Dry the cables and terminals. Don't use
grease on the bare metal inside the cable terminals to
prevent corrosion. Grease is an insulator. ElectriCity will
not flow through it. A plastic ignition spray will protect the
terminals after you have cleaned and reinstalled them.
Check the battery, including water level, often. Keep the
carrier and hold down hardware clean and free of corro-
sion and chemical accumulation.
Battery Charging
Both sets of batteries will be kept charged by the chassis
charging system while on the road. The AC/DC power
converter will charge the coach battery when plugged
into 120-volt service. On those occasions when the
battery needs to be charged from a different charging
source, please follow these safety guidelines:
