My 2 bilge pumps in the aft bilge are not working? I checked the switch and it is good the float switches are fine and the pumps will run if connected to the battery. For some reason I am not getting any power to the main switch:huh: The curcuit breaker seems good so what could it be. I don't have my port battery in yet but that shouldn't have anything to do with it does it?
Thanks
Bob:thumbsup:
 
The crimp terminals connecting the float switch and pump to 12VDC are corroded. Cut them out and replace them, but check the wires you strip to be sure you have cut them back to solid copper that isn't corroded.
 
Not sure that is it. I cut the wires back and put a test light on them and I had no power:smt100Seems like I am not getting power to the main switch.
 
If there is no power going to the main switch then my guess is that bilge pump is suppose to be connected to the battery you have not put in yet.

My 220DA starboard battery has a few wires connected to it's terminals that the port battery doesn't have. I'm thinking it's probably the always-on power for AM-FM radio memory, and bilge pump power...which should all work regardless of whether the battery switch is on or off. My guess is if you look at the wires to be connected to the port battery you will find the bilge pump wire there.
