I have a 99 XP and when I plug the key in, the bilge pump makes no noise. I ran power directly to it and it works. Any ideas? If I remember correctly, it grounds in the MPEM, could this be an MPEM issue? (Please say no, please say no....) Thanks!
Hhmm...on boats,,,they all have automatic setting,,,the pump is always wired to the battery,,,besides the helm manual switch,,,not sure if that is how yours is wired,,,and does it have an external float switch?,,,or internal?
