50 ~ volts in door/doorframe, intermittently
Greetings friends, I have a 2014 Coachmen Leprechaun C21QB with about 30K miles on it, and last week It began shocking folks at random in the door frame/door steps region. It's happened at 3 separa...

When a loose or corroded connection occurs in the AC Hot or AC Neutral wiring there is heat generated at the bad connection because of the high currents through the bad connection.
On the other had the only time a bad connection in the ground wire is going to generate heat is when there is a fault, such as a HOT to GROUND short.
So this bad connection we are looking for is typically only conducting less then 5 milliAmps (0.005 Amps) which is the approximate trip point of a GFCI. So this small amount of current is not going to heat up the bad connection like it would if in the Hot or Neutral wiring and that makes it difficult to detect. As nomad297 stated, wiggling a suspected point of the bad connection can help in detection but you need to making measurements/observations at the same time.
