Shoutout to the guy at the Phoenix MRO who helped me trace that intermittent fault

Spent two full days chasing a ghost in a G1000 autopilot, and he walked over with a different brand of breakout box that finally showed the glitch. Anyone have a go-to method for those random voltage drops?

Know that feeling all too well. Sometimes it just takes a fresh set of eyes, or in this case, a different piece of gear. Glad you finally tracked it down.

Ugh, I have to disagree. That just sounds like throwing parts at a problem. If your first breakout box can't find it, maybe the real issue is the testing method, not the tool brand. Relying on random gear swaps is a shaky way to fix things. It sets a bad habit for troubleshooting.

Last year I had a weird voltage drop that my Fluke meter just wouldn't pin down. Swapped in an old analog Simpson from my dad's garage, and the needle showed a flutter the digital readout missed completely. Sometimes the older tool just reacts differently to a gremlin in the system.
