I enjoy the feedback.
I understand the I do not know enough to 'get by'. I had a marine electrician overseeing my work ( just to make sure ).

I would rather 'learn' how to, instead of throwing money at 'easy' solutions.

Didn't originally work in Mozilla Firefox either.

Good diagram of isolating the manual from the auto circuit through the same switch. I like that approach better than what the OP has described they will do (although reportedly hasn't connected the manual lead to anything yet, which probably isn't too cool either) Be careful OP.

However, the OP's pump does not require a float switch, so skip that and connect directly to the third wire from the pump. Also, the auto/off/manual switch should either be fused or, more likely, there should be an inline fuse between it and the battery.

In the harsh marine environment, something is always in need of repair. Margaritas fix everything.

Ok, I went down to the boat last night ( after a week away ) and the pump was 1/2 covered with water ( about 3-4 inches ).
Bilge pump was not working.. very strange..

I can press the 'check' button on the back of the pump and it comes on perfect, and when the water gets to a lower level, it turns off.

this is the 2-3 time I have noticed that the pump does not come on automatically, and I have to hit the 'check' button.

It is wired correctly, so what would be the issue here?

thanks.

Easy, bad float switch. ALL float switches go bad. The electronic ones get a coating of crud and fail to trip, the mechanical ones jam. So far the only really 100% reliable way to rig a float switch, is to have a crew stationed in the bilge with his crotch just above the waterline. When the cold water rises, he'll let you know to turn on the pump. (Works best in icy water.)

Yeah, well...seriousaly, the best you can do is to have TWO float switches so that one failure won't stop the pump, and at that point with pumps being so reliable, might as well have two whole pumps in there.
