I am new to this site, so let me start by thanking you in advance. I have a 1977 Georgie Boy. I have a problem with my 12V system. When I plug my coach in, the lights will click on and off intermittenly. I had a bunch of wiring problems in the dash. I have cleaned up most of the problems, but still have some open wiring. The thing is, I had no problems with the 12V until I started cleaning up the goofy wiring. When the lights flick on and off, I heard a clicking noise around a firehydrant looking solenoid by the batteries. I am completely lost and would greatly appreciate any advice at all. What I can tell you is that I get 120 out of the outlets when plugged in.
