Filter is a Sta-Rite 21" 200# sand filter. According to the owner's manual it is sized for the 1 1/2 hp pump. The wires at the end are what melted. He took the end of the motor casing off and it's the wires exposed there. Again, I've read several posts online about this particular pump model having a meltdown with those wires burning out, so it could be a manufacturing defect. I don't know; kind of a moot point though because even after rewiring it's still dead as a doornail, and even if he could've got it running again, we were going to replace it. Hubby was just trying to revive it long enough to give us shopping time for a new pump. Unfortunately, with the heat and no pump, we don't have time to do too much shopping around and need to get something running again ASAP. If we really could go with a smaller pump that would be super, since I'm guessing a 1 hp pump might use less energy. It sounds like given our filter going to a 1 hp would be a better idea? Thanks in advance.
