Found a better way to trace intermittent faults in old 737 wiring harnesses
I used to just wiggle wires and hope for a flicker on the test set, but after a 3 hour chase on a 400NG last month, I started using a cheap thermal camera from Harbor Freight to spot hot spots under load. The heat showed a bad crimp behind a panel I would have never pulled, fixed it in 20 minutes. What's your go-to method for finding those ghosts in the system?

Tried that thermal trick on some sketchy cabin lighting circuits last year. The camera showed a warm terminal block that looked fine during a normal visual. Saved me a ton of time chasing a bad ground.
