This weekend at the rally my bilge pump went out, today when I started digging it out I found I had two bilge pumps one looked disconnected or the wire had come lose. I am thinking there must be an auto function on one of these pumps but I'm not sure. One of the pumps has three wires one black and two brown and the other only has a brown and a black. There was two brown wires that were lose I think those might be some kind of auto switch that is activated by the water level. Is there any one that can tell me or draw me a picture of how these are wired up and how I can test this auto function if that is what it is? Both pumps are working but there is a lot of junk in the bottom and they are burred under the gas tank which I can not get out. Help![]()
