Auxiliary Start System
(If Equipped)
You can use the Auxiliary Start System to start
the chassis engine or the generator with the house
batteries if the chassis batteries are discharged or
start the generator with the chassis if the “house”
batteries are discharged.
To use the Auxiliary Start System to start the
chassis engine:
1. Be sure the motor home is stopped.
Shift the transmission to N and apply
the parking brake.
2. Press and hold the Auxiliary Start switch
on the instrument panel.
3. Start the chassis engine with the
ignition switch.
4. Hold the auxiliary start switch for at least 30
seconds after motor starts before releasing.
To use the Auxiliary Start System to start
the generator:
1. Press and hold the Auxiliary Start switch
on the instrument panel.
2. Press the Generator Start switch until the
generator is running.
3. Release the Auxiliary Start switch.
120-VOLT SYSTEM
This system provides grounded 120-volt AC elec-
trical service for appliances. This system includes:
• the generator
• the main electrical power cord (“shore
chord”)
• charger and inverter
• residential refrigerator
• air conditioners
• AV equipment
• microwave ovens
• dishwashers
Your motor home is equipped with a heavy duty,
power cord. It is commonly called the “shore cord.”
This cord is used to connect to external 120-volt
AC service. The cord and connector is molded
together to form a weatherproof cable assembly.
Do not cut or alter the cable in any way. Do not
remove the ground pin in the cable connector , or
defeat the ground circuit in the motor home.
To connect the power cord to external service,
turn off both the circuit breakers at the external
service and the motor home power distribution
panel, push the plug straight into the receptacle.
Power Inverter
The inverter uses 12-volt DC power from
the coach batteries and transforms it into
60-cycle, 120-volt AC power to run some of the
appliances in the motor home.
NOTE
The roof air conditioners cannot be operated on
power supplied by the inverter. The motor home must
be plugged into an external AC service or the genera-
tor must be operating to run the air conditioners.

NOTE
There is an inverter disconnect switch located inside
the inverter compartment. The disconnect switch
needs to be turned on for normal use of the inverter.
The switch is intended for motor home storage and
will be turned off when the motor home is delivered.
Failure to turn off the inverter disconnect during motor
home storage could result in discharged batteries.
TO ENSURE FULLY CHARGED BATTERIES CAN
START ENGINE, RUN YOUR MOTOR AT LEAST
ONCE EVERY 30 DAYS.

WARNING
Do not operate the 120-volt electrical system without
a proper ground. Electrocution or severe electrical
shock could result.
!
CAUTION
Switch off the 50 amp main breakers located in the
120-volt AC load center (breaker panel) before you
insert or remove the 50 amp power plug. Be sure
to insert or remove the plug straight into or out of
the receptacle. The neutral and both 120-volt volt
pins should make contact at the same time to avoid
excessive voltage on one leg of the circuit that could
damage 120-volt appliances.
