hot frame

While washing my 86' Sovereign I got bit when I touched the skin. I was plugged in to ac. I got my meter and it read 52 volts ac. Now that is a strange voltage. Any thoughts?

Sometimes when washing a trailer water gets to places it normally doesn't so it's possible that is the only problem or could be a bare wire that only shorts when wet.

To start checking for other problems start by turning off all 120 volt breakers in the trailer and then check for that voltage, then turn the breakers on 1 at a time and recheck for voltage till it comes back to narrow down which circuit has the short.

Before checking the trailer check your AC source at the house. Make sure you do not have a polarity reversal. If the house checks out OK than start in the trailer as noted above.

It definitely sounds like an a/c line polizarization reversal.
I would check that first.

if you have an electric element for heating your water, they often go bad and leak power to the shell. It can account for the strange reading on your meter. However, I am also concerned that you could have a defective ground from the trailer back through the power cord. With that high a voltage on the shell, something seems wrong with the ground path you have (or don't have, so it is going through you).

In AC circuits there is no polarity. But it sounds like you may have a case where the hot wire and neutral are reversed. But that is not your only problem.
If the current from the hot wire can be felt on the skin of the coach. There is not a proper earth ground.
The neutral in the coach should not be connected to the ground plane in any way, inside the trailer. It should be a floating neutral.
If you don't have electrical knowledge. Find someone who does. Get this problem resolved.
