Weird Electrical Issue/ Need experience of RV.net

Thanks, will track power to pump tonight. Idiot lights come on. I've been poking around at this thing by myself, likely get my wife involved. LOL! Long way back to the tank to hear the pump.

Decided maybe I've been looking at it the wrong way. Called a hotrod buddy of mine, and first thing out of his mouth was "bad ground". "Too simple" I said, and immediately did some "grounding" improvement work.(He's rarely wrong) We'll see if that helps in tonight's session.
