Stray Voltage?
My RV has a stray voltage problem, and I'm wondering if anyone has any good ideas on how to find or fix the problem. My daughter complained to my wife that she thought she was getting shocked when ...

I had to work again and didn't get as much free time today, but I did get a chance to show the office guys the voltage I was reading off of the outside of the pedestal to the dirt and he was quite surprised and put it first on the list for the maintenance man (a former electrician) to look at tomorrow. I poured a cup of water on the ground where I put my black lead into the dirt trying to get a better ground and got about 10V.
The fun part cam when I showed him I had about 5V comming from my RV even when I had all of my electrical disconnected and turned off. He suggested I use the jumper cables I still had out from yesterday and clip it to the water pipe that was also right there and see if it would help ground my RV. Thought it might be worth a shot but then had an idea and tried to test the spigot to see if maybe since the water pipe was right next to the pedestal if maybe someone might have already hooked a ground to the pipe and sure enough the water pipe had 6V on it. So I disconnected the hose from my RV and the voltage from my still unplugged and now waterless RV was now less than a volt. :)
Finally think I found the source of the problem. Even when testing from the back of the pedestal and using the water pipe for a ground instead of the dirt the voltage only shows about 5V, which makes sense as in Mike's website he explained that a volt meter only measures voltage differences, and that was about the difference in voltage of those two items.
It will be interesting to see what the electricians find tomorrow.
