Old timer showed me a trick for tracing wire bundles

Had a guy in Pensacola who'd been doing avionics since the 80s. He told me to use a tone generator and probe instead of chasing wires by sight in tight spaces. Saved me 2 hours on a 737 harness repair, anyone else use that method?

Nah, tone generators are fine, but I still prefer pulling schematics and tracing manually.

Oh come on @perry.evan, I gotta disagree with you there. I used to be all about tracing everything by hand too, but tone generators saved me so much time once I actually learned how to use them right. They catch frequency issues way faster than poking around a circuit board with a probe, and you can pinpoint dead components without even touching the thing. Plus when you're working on something with surface mount parts, manual tracing is just a nightmare compared to letting the generator sweep through. Different strokes for different folks I guess, but once I switched I never looked back.
