How did you jump power to the pump to get it to work; ran positive and negative from battery to pump or jump from a local source?
Is 12V getting to the float switch? If yes when the switch is lifter does 12V come out the other wire?
However since the pump isnít working from either the float or helm I would assume itís either the positive or negative connection to the pump thatís open.
