Finding Damaged Section of a wire in a wall

If it was that easy I would have done it. The wire goes through and around a few steel beams that are the main supports for the building. It makes a few zig zags along the way which would be a PITA to route through. Not to mention the dozens of zip ties I used to keep my cables seperate from the power lines in the wall. On top of that they are all stapled (big staples you put in with a hammer…). It just ain’t gonna happen without tearing out drywall.
