DAE think a cheap heat gun beats a $400 IR thermometer for finding a bad connector?
Spent two days last month chasing an intermittent autopilot disconnect on a King Air and the IR gun kept reading normal at every pin. Finally grabbed my $30 heat gun, warmed the cannon plug for 20 seconds, and the resistance jumped right where the wire was frayed inside the backshell. What's your go-to trick for catching a fault that only shows up when things get warm?

A guy I used to work with swore by a hair dryer on the old Beech 1900 brake temp sensors, which sounds silly until you watch a thermal fault show up in 30 seconds that a meter missed all afternoon. His trick was taping a shop towel over the part first so the heat spread slow and even instead of cooking one spot. I still keep a cheap Conair in my go bag next to the good meter.
