Bilge pump wiring
I just purchased a 3257 1988 carver Montego sedan I’m trying to fix wiring problems. The switch panel indicates two bilge pumps. However, there are three bilge pumps, the aft bilge pump and the mid cabin bilge pump both work as designed the forward bilge pump has two wires, and there is no power Have a good ground wire but the positive wire is dead I’m trying to figure out where it goes. Any suggestions? Thank you.

Re: Bilge pump wiring
Power for bilge pumps should always come from the batteries with a breaker in between. My bilge breakers are under a step. Make sure those are all on first. Then trace back to the pump from there.

Re: Bilge pump wiring
Welcome aboard. Does your forward bilge pump come on when the mid cabin pump is powered up? They might be on the same circuit. I've seen them hooked up this way before.

Thanks for getting back turns out the forward pump is a stand alone has no switch and runs straight from main battery breaker found a push button breaker in the back of a locker under the helm seat reseat the breaker easy peasy works now
