Section 6: Electrical System
Load Center
The Load Center contains 12VDC fuses and 120VAC circuit breakers for almost all of the
electrical appliances and circuits in the RV. The 120V main breaker may be located in this
panel and will turn off all 120-volt power to the RV. Load center location, appearance and
configuration may vary by model. Refer to the diagram inside the load center for specific
fuse assignments.
Motor homes may have separate small panels for breakers and fuses. They are normally
located in close proximity to each other typically in the bed platform. The converter is
mounted separately, typically under the bed platform.
The auxiliary start switch can momentarily connect both the house and chassis batteries
should the chassis battery become discharged.
To operate, depress either the “Aux. Start” switch (located on the front driver’s dash) or the
Battery Boost switch on the driver console and hold it down. While the “Aux. Start” switch
or Battery Boost switch is depressed use the ignition key to start the chassis engine. Release
the “Aux. Start” switch (or Battery Boost switch) after the engine has started.
Automatic Transfer Switch (ATS)
Your motor home is equipped with an Automatic Transfer Switch with built in reverse polar-
ity protection. The ATS is microprocessor controlled and will automatically detect which
power source is being used (generator or shore power) and allow power from that connec-
tion only. You will not have to plug and unplug power to the coach if you decide to run the
generator.
If you plug into shore power, the ATS will pass power to the motor home. If the generator
is started, it will override the shore power input (called generator dominant) and supply the
RV with electrical power from the generator. When the generator is shut down, shore power
is restored.
There may be a slight flicker of the lights when the ATS changes over from one to the other,
but there is no real interruption of power.
The ATS will disconnect from shore power completely if the power coming in is not high
enough quality (i.e. either low/high voltage, or low/high frequency).
When the generator is operating, it powers the inverter/charger which in turn functions as a
multi-stage battery charger to charge the house auxiliary and chassis batteries.
Refer to and follow safety information found in the manufacturer’s troubleshooting guide
found in your warranty packet.
