I had the shore line hooked up last night, This
evening after the temp went down I went out
to work on the GMC...There was no 110 AC. The
GFI on my house was clicking. I replaced the
GFI to no avail! I have a direct short
somewhere.... Will remove the Shore Line and
check for Shorts. The Screw on the Breaker
was badly corroded, Cleaned that, No Change.
I have nothing plugged in the inside outlets.
Even unplugged the converter.
Any Ideas?

Yes Arch,
Makes sense, I am a builder so have
done alot of wiring....Maybe it is
as simple as the GFI kicking off...
Due of course to some strange wiring
system. However, I have been hooked
up to that GFI for weeks, On and off.
Thanks,
Rob

Arch,
Went out and unpluged from the GFI, Everthings
working now. Makes me wonder if theres a power
leak somewhere???? Its My understanding that
a GFI doesnt need to be grounded to work?
I have to tell you that I appreciate your help.
You and everyone else who respounds to my dumb
questions.
Thanks Alot,

Ok:

Ther are two types of GFI. One is for residential style use andtrips
extremely easily. They are trying to protect you from frying yourself
while standing in a puddle of water. It dose not take much to trip it.
There is a second level that is for industrial use. It takes a great
deal more to trip, but still not a lethal dose. If you are useing one
for outside use make sure it is the one that requires a larger Ground
fault voltage to trip it. The wiring in your GMC is at least 20 years
old and exposed to a much harsher enviorment than any thing around your
house. If your measurements of the electrical system in the coach are
fine then you should be fine. But make sure that you take the proper
measuremnts between ground, neutral and hot.

Thanks for the info Marcus. Maybe I will
look for a Commercial GFI. I really do
like the idea of the extra protection.
