The inverter converts 12 Volt power from your house batteries to 120 Volt power for your
motorhome. The inverter will power the entertainment circuits, which include, the TV and
DVD player. Be aware that batteries are a limited power source and will quickly discharge
under high loads.
The AC electrical system provides grounded electrical power to your 120 Volt electrical
appliances through the external shoreline or your power generator. The shoreline is a one-
piece molded cord that provides a weatherproof cable assembly. Included in this cord is
a grounding pin. If any adapter or extension cord is used, ensure the wire is sufficiently
sized for the amperage of the motorhome. Be sure the grounding pin is maintained.
motorhome. Failure to provide sufficient electrical power can cause low voltage and/or damage
to your appliances and motorhome.
AC receptacles are located throughout your unit for your convenience. Certain circuits
are dedicated to individual appliances (i.e. air conditioners, microwave/ convection oven)
because of load requirements.
Your motorhome is provided with a Ground Fault Circuit Interrupter (GFCI) receptacle

GFCI

located in the bathroom which also provides protection to all outside receptacles. The
GFCI is designed to limit the time of exposure to an electrical shock caused by current
leakage to the ground.
1. Press the TEST button.
2. The RESET button will pop up. If the RESET button does not pop up, a
loss of ground fault protection is indicated. DO NOT USE that outlet
or other outlets on the same circuit until a qualified RV electrician has
checked out the electrical system.
3. To restore power, push the RESET button.
The Battery Control Center (BCC) houses all the fuses for your auxiliary coach circuits. The
BCC is located under the hood. Inside you will find a series of fuses for the extra circuits
not available on the automotive or interior house 12 volt fuse boards. These style fuses
are available at any automotive or RV store. If it should become necessary to replace any
of these fuses, be sure to replace them with the same style and amperage rating. The
circuit wiring is sized for that particular amperage. The BCC will sense when to charge
either set of batteries. If the voltage falls below the minimum requirements, the BCC will
switch the charge to that set of batteries. Terminals inside the BCC are available for testing
its functionality. This testing should be performed by a qualified RV technician.
Electrical output devices, extension cords and adapters must be
grounded and suitable for the electrical requirements of your
The GFCI should be checked once a month to assure proper
operation. To test the GFCI:
If the outside receptacles do not work, check the GFCI receptacle
to make sure the reset button has not been tripped.
