Unpopular opinion: the 3 hours I spent chasing a phantom fault in a CRJ-200 last Tuesday taught me more than a month of classroom training
Turned out a wire bundle behind the avionics rack had rubbed through on a bracket, but the intermittent fault only showed up when the cabin got cold, so I want to know how you all track down squawks that only show up under specific conditions instead of just reseating connectors and hoping it sticks.

Last winter I watched a guy spend 40 minutes wiggling a cannon plug on a 737 that turned out to be a chafed wire in the wheel well, so the whole "figure it out by hand" thing is way overblown. Freezing the rack with a can of air or running the pack to cook the cabin is fun, but it just adds more dark time to your logbook, and most intermittent faults get fixed by a solid visual check and a new zip tie anyway. Wasting three hours fishing beats the classroom, sure, but the guy who reads the FIM and swaps the part in 30 minutes still goes home on time.
