The old pump had 2 positions, on and auto.,
4 wires. I ordered a replacement and it only has 3 wires.
When I wire it the way I think it should go, it will run in one position and throw the breaker in the other pos. I called the Mfg. they could not help because they don't know how the rocker is wired.

Not an official MC diagram, but its the basic info. Don't know why the original would have 4 wires.

Maybe this is it.

Sorry Bob, can't help you with that. Was only being sarcastic at your 'bilge' problem. Ricford has it covered. good job.

FYI, the new pump has three wires. (See Diag).
Been in contact with my Mastercraft dealer. (200 mile away)
He gave me some suggestions.. So I’ve pulled the dash to check wiring on rocker switch, Blew the circuit breaker. I have a spare circuit breaker in the panel.. But good old MC used one different one in the panel. Guess which one that was? Will be ordering a bilge pump breaker Monday.
