How to Discover Source of Hot Skin
My trailer is parked under a metal carport on a dirt pad covered with rock. It has been raining and the ground under the rock is damp or wet, depending on where you are under the carport. Last evenin...

The meter has something like 10 M ohm input resistance. It will pick up radio waves. That's what you're reading. However, that's not what gave you a tingle. Either you imagined it or there's something else wrong with the electrical system. Probably an open, or sometimes open ground in the extension cord going to the garage.
If there's an open ground then you'll see 60Vac from chassis to ground. This can give a slight tingle when ground is wet. The 60V is created from a capacitor voltage divider within the converter. Nothing to worry about as it has about 5 kohm resistance.

What is the problem here? I wouldn't think you would feel about 1/4 of a volt, but I did, at least when the ground is damp. How could there be AC Voltage (as small as it is) when the trailer is not plugged into shore power? Where to start? How does one figure this thing out?
