[QUOTE=Rocky Road;1257917]Checked power coming into power select switch and discovered that one leg was dead and other leg showed 240v to ground….no bueno! /QUOTE]

I am having a very hard time with that one. I do not see that as being possible in a standard 120 / 240 volt situation. One leg cannot possibly show 240 V to ground.

Possibly one of the 2 120 V legs was on the ground terminal in the plug? In that case the ground tab on the 50A twist lock would had 120 V on it and quite probable so did the frame of your rig.

A am glad I can do my own service work on all of my RV systems. Some of the stories I read here scare the heck out of me.
