Shore Power GFI Problems

[Adrian]

Before I go tearing into the wiring I would like to know if this is a common occurrence or a problem.
When I plug the clipper into a GFI circuit it pops the shore circuit. I have pulled all the fuses in the inverter and set all the breakers to off. But still it pops the shore GFI.
Thanks

Adrian do you by chance have your roof air on when you pluged in if not you have a direct short most likely in the inverter itself,make sure the airs off then plug it in, how about with the gen ?

[Adrian]

Jim,
I have the roof air off.
The gen when working, seems to be fine. The internal GFI doesn't trip.
It only happens when I plug in to shore power.
Do you know where I can get some info on the inverter?
I have a 1977 model.
Thanks
Adrian

Adrian,
send me you email address and I'll email you the book or the main pages mine is a 77 also but I think the problem is in the shore power not your rig is this you house or a camp ground if it's your home try a none gfi plug you might have a bad gfi I have a 20 amp plug set up for mine

Adrian did you get the info

[Adrian]

I did,
Thanks Jim, the info defiantly helped. Now I know why I had to sometimes tap on the fuse area to get the 12vdc from the house bat to come on.  Behind the fuse area is the automatic power switch that switches from the converter to the bat; it has gotten very dusty over the years and sometimes sticks. So a good blast of shop air fixed it rite up.
But this shore GFI problem is driving me nuts. I'm in the process of isolating every wire and seeing which one trips it. I had a friend who is an electrician come over yesterday but he is also stumped.

Adrian,
Do you have a DVM or VOM or access to one?  Has the plug on your Clipper been changed? (If the plug is a molded plug ie all one piece, it has not been changed, if the plug has a screw in the center of the back it has been changed).  If the plug has been changed, remove the screw from the back of the plug to expose the wires. Holding the plug so that the prongs are pointing down (so that you are looking at the back of the plug) hold the plug so that the ROUND pin is at the top, the  green wire should be connected to the ROUND pin, the pin on the left bottom should be connected to the Black wire, the pin to the right bottom should be connected to the white wire.  Is this the way it is wired? Check this then email me at eristow@att.net for the next check. Ed

We once had a family with a Clipper they had just bought move in next to us in a campground. They were also tripping the GFI breaker on the pole. We isolated his problem to the refrigerator. I opened the outside door and unplugged it, and no more problem. Apparently it was leakage to ground from the fridge heating element.

Thanks all,
GFI problem solved. There was resistance between the ground and the neutral bar on the breaker box. I traced it back to faulty wires connecting to the receptacle in the refrigerator box. I guess after 25 years it finally went. Actually this maybe something other might want to check out. It looks like the wires were the ones from the factory. The insulation on them is rather soft; with its location over the wheel well it gets a lot of vibration. This is what I think cause them to rub away the insulation.
Again thanks for all your help.
