Learned the hard way about bad ground wires on a King Air 200
Last Thursday I was troubleshooting a NAV 2 that kept dropping out on approach. Spent 3 hours swapping boxes and checking connectors before I finally looked at the ground strap behind the rack. It was corroded almost all the way through, looked fine from the top. Replaced it with a new strap and everything worked perfect on the next flight. Made me feel pretty dumb for not checking the simple stuff first. Anyone else ever chase a ghost fault that turned out to be a ground issue?

Yeah but that's not really a ground wire issue, that's a bonding strap problem.

Bonding strap is part of the ground path though, @brian_kelly91. Thin strap gets brittle, cracks, and you lose continuity. Same problem in the end.
