Automatic Bilge Pump Won't Shut Off
Last year I installed a small bilge pump with a built-in float switch. I also installed an auto/manual/off switch and generally left the pump in auto mode.
After a long spring that involved a rudder rebuild and assorted related problems, I launched last week. I've discovered that the bilge pump no longer reliably shuts itself off. If left on auto, it will run until it's quite hot.
The pump is a Seasense Auto 800 GPH model (manufacturers' info here
Any suggestions on how I might diagnose the problem?
