My pump has an electrical short in the well. Short shows on all three leads on multi-meter. Pulled pump for visual inspection but saw nothing wrong.

The motors are known to have a direct shorts in the motor !!!

First of all, the splice kits that usually come with these pumps are not very good. Its best use electrical tape and a product called Scotch Kote. Making these splices takes practice. As for your short, disconnect the supply cable at the well head from the pump wire and check for a short in the underground cable to the well. The wire down the well is the problem a lot of the time. It rubs on the wall of the well and gets damaged. If you have steel well casing, check for the short from each lead to the well casing, not the ground wire.(The pump has to be installed in the well to do this) You will always get a short reading using the ground wire. If the pump is out of the well, hook one lead of the multimeter to the pump motor mounting bolt and the other to the motor lead. If the motor is shorted, you will get a reading. In closing, it is rare for these motors to short out, but no so for the wire.
