So you had two intermittent shorts in different places on the same pickup? I'm guessing the pickup initially had a problem and the previous owner created another issue with his "fix".Ok, found another issue. Everything checks out UNTIL I put the pickup screw in (lower one near the hole). Once the screw is in, shorted. Must be a bare hot lead inside the can right at the screw hole.
On a positive note, you are getting better at troubleshooting
