This is my setup. The switch did have a piece of debris holding it open. I expect that could happen eventually and thats why I have two pumps, individually wired to a separate battery. I can live with aone dead battery but when one switch kills both batteries sometingwong!
I need better switches and to figure out why both batteris die.
