Strange electrical problem.

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.

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'm an idiot.

Checked my adapter and it he ground is broken off

Fairly common actually.

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

Useful tool

When the RV chassis/ground is allowed to float (ie like others said, no ground conductor to Earth) and while 120 VAC Hot and Neutral are connected, the chassis/ground will attempt to establish itself 1/2 way between Hot and Neutral due to capacitative coupling between the Hot, Ground and Neutral circuits.

This leaky capacitative current path is enough to feel a tingle when you made a conductive path from chassis to Earth but not enough to effect a serious shock. It is a friendly warning of a serious faulty ground condition in that your first level of safety is compromised.

So how can I check if the problem is really fixed? Multi meter?

OOP,

Did you look at the "useful tool" link I posted? If you use the foreign voltage detector by probing the skin/coupler and other parts of the rv, it will light up- indicating there is still voltage present. If it does not light- your condition has been fixed. In basic terms, use a good surge protector at the pedestal- it will tell you if something is mis wired. You can also use outlet testers or make your own if you like. Google "RV Electric" and you'll gets lots of good info.

Before I plug in this goes into the shore station.
After I plug in this goes into an outlet inside the RV.



Let's you know what is going on at the shore station and when plugged inside it tells you when something does happen later.

I sure wouldn't just assume the problem has been "fixed" ... get a polarity tester like that recommended by rockhillmanor and check your source supply to make sure it's correctly wired, no wires loose, etc. Assuming it is then plug in your trailer and use the same tester in the trailer to confirm there aren't any errors being introduced by the trailer. Assuming no errors are found it's probably safe to say you've found the source of your problem but from here on in do what rockhillmanor and I and many others do every time we camp - test that source supply with a polarity checker before you plug in.
