Rant: That week where I chased a ghost fault on a 737 for 5 days

Last month I had a plane coming in with an intermittent P2 stall warning that would only show up on the third leg of the day. I swapped the proximity sensor, checked the wiring, even re-terminated the connector at the LRU. On day 4 I found a tiny nick in the shield wire inside the wing root that was grounding out after the plane got warm. Cost us 40 man hours and 2 canceled flights. Has anyone else dealt with a fault that seemed to disappear every time you put a meter on it?

Spent three days chasing a wire fault that just turned out to be a loose ground screw.

26 years in and it's always the damn ground screw hiding in plain sight.
