This morning I went out to clean the trailer and I have no power. We have a Progressive Industries surge protector/power monitor in it and it shows no error code and voltage coming in to it is good. ...
John, the twelve volt system works fine. There is no AC power. As unusual as it seems, the bathroom GFI appears to shut down the entire AC system. I will replace that outlet today and see if it solves the problem. Since the power works for a few seconds when I reset that outlet, it does seem likely that the outlet is the culprit.
