Boat is a 1997 Ranger R80 Sport. Recently my port side live pump stopped working. When I turn on the switch, it illuminates, so I not the switch is getting power. I have also supplied power directly from the battery to the pump, and it works fine. So I know the switch is powered, and pump is good. So obviously something is wrong between the switch and the pump, and the only thing there is a 12 guage brown/white wire. Is it common for a wire to just go bad? possibly punched or rubbing somewhere that could cause it to fail?
