Welcome to iboats!:cool:

It sounds like a bad ground for those circuits and they are going through the fuel gauge sending unit to get it (unsuccessfully, of course). Check the ground wires for the blower and lights.

Times 2 on the ground. Check under the helm for a ground bus, as well as in the bilge area. Chances are, that's where your blower motor picks up it's ground...

Here's how your float and pump are wired...

Check the fuse at the helm, and manually test the float with the test knob or lever...

I bought a new bilge. Everything is in working order now. Thanks for the help
