Just realized a corroded ground strap under the floor panel of a Citation XLS was the real culprit for a phantom autopilot fault that took me three entire days to trace.

Ugh, ground gremlins are the worst. I read a maintenance article once that basically said half of all "weird" electrical faults end up being a bad ground, and I totally believe it. @brown.simon's story about the firewall bolt is a perfect example of how one tiny spot of rust can make a whole plane act possessed. It's always the last place you look, buried behind everything else.
