Hi, i'm new here and want to say what a great site.
I'm looking for ideas to solve for a short in a run of mc cable. It's between the hot, neutral, and sheath on a 50' run that goes up and down and around a stairwell to an outside light and there's no way to fish a new wire. It's finished drywall and i suspect the culprit is a drywall screw. I isolated both ends from the boxes and fittings and energized the sheath and hot wire then attempted to find the offending screw with my 'hot stick' [non-contact tester]. the tester, which is not overly sensitive at other times, glows along the entire run one foot to either side.
Any ideas short of buying some expensive new tool? Thanks in advance, zero
