Strange electrical problem.

[samhain7]

I have a wierd one today.

I was showing my father in law my distribution hitch. I was standing barefoot in the driveways and I touched the steel unpainted L pin that holds the bars to the L bracket attached to the trailer tounge.
Guess what. I got a mild shock. My father in law touched it with his shoes on and got nothing of course...
I also touched the painted A frame tounge of the trailer and didn't got a shock. It is only the unpainted L pin.

Any ideas on this one....

It's a good idea to have one of these as well:

Fairly common actually.

If you are plugged into a 120VAC 15A/20A house receptacle perhaps the ground lug is missing or not hooked up.

ALL THREE wires needs to come to the trailer from the house (WHITE-BLACK-GREEN)...

I am assuming that you are plugged into shore power..
Sounds like you have a faulty ground. Check the ground wire to the frame. Mine is near the steps to the door on the frame. It might be corroded, loose or missing.
