Grounding is your personal protection from
electrical shock. Your RV has a ground fault
current interrupter (GFCI) receptacle outlet
engineered into the 120-volt AC electrical
system. It may have additional outlets wired
through, and protected by, the GFCI. Its
function is to reduce possible injury caused by
electric shock. The GFCI will not protect
against short circuits or overloads.
Test all GFCI receptacles monthly
The 120-volt AC electrical system must be on
in order to test the GFCI.
1. Plug a 120-volt AC electrical device into
the GFCI receptacle outlet.
2. Push and release the RESET button (the
120-volt AC electrical device should
operate normally).
3.
Push in the TEST button.
4.
The RESET button should pop out
indicating the GFCI receptacle has been
“tripped” and the 120-volt AC electrical
device should cease to operate.
5. Push in the RESET button again and it
should hold. If the GFCI did not trip, do not
use the GFCI receptacle outlet or those
wired to it. Call your dealer for repair
assistance if it does not hold and pops
back out. Any faulty equipment must be
repaired before your RV is used again.
Although your RV’s exterior power receptacle
(if so equipped) is not a GFCI receptacle
outlet, it is wired through and protected by the
interior GFCI.
If your power cord is connected to 50-amp
service properly and the 120 VAC system is
not operating, we recommend you test all the
GFCI outlets, check the circuit breakers in the
load center and test your external power
source receptacle before calling your dealer
for assistance.

When you purchase and use 120-volt
appliances, remember your RV is limited to a
maximum load of 50 amps. When camping
and traveling, remember each appliance and
120-volt accessory places a load on the RV
electrical system. You may periodically trip a
circuit breaker if the combined load of these
appliances and accessories exceeds your 30
amp rating.
You can determine the amperage rating of an
appliance by dividing the watts used (usually
found on a label or plate affixed to the
appliance) by your RV’s supply voltage.
For example: 1200-watts divided by
120-volts AC equals 10-amps.

The majority of your RV lighting is powered by
12-volt electricity. The 12-volt DC system is
composed of components that will operate
when the following conditions are met:
□ Power is supplied by the chassis
alternator when the engine is running.
□ The converter will supply interior 12-volt
DC power when the power cord is plugged
into a 240/120-volt external power source.
The converter will also charge the
auxiliary battery in most situations.
□ The house batteries power many interior
12-volt components including the lighting
fixtures, water pump, 12-volt motors, 12-
volt appliances, etc.

Your motorhome is equipped with an auxiliary
start switch which can momentarily connect
both the house and chassis batteries should
the chassis battery become discharged. To
operate, depress the "Aux. Start" switch
(located on the front driver’s dash) and hold.
Now, use the ignition key to start the chassis
engine. Release the "Aux. Start" switch after
the engine has started.
