Mine will not come on and drain the live well.

Found a blown fuse and thought, this was easy. Changed the fuse, but it still doesn't come on, so I"m unable to drain my live well.

The pump that is designed to fill it will come on just fine. As does the bilage pump.

Any ideas would be appreciated on what to do to trouble shoot this?

Check and see if it has power at the pump. May have a bad pump. What kind of boat? Mine just has a valve to drain the livewell.
