Spent 4 hours chasing a phantom avionics fault on a Citation

Kept getting an intermittent autopilot disconnect warning, but the logs were clean. Turned out to be a tiny bit of corrosion on a ground strap behind the main panel that you'd only see if you moved a wire bundle. I mean, it looked fine from the front. Anyone else had a simple ground cause a huge headache like that?

Always check the grounds first, saves so much time.

Yeah checking the grounds is key. I had a weird flicker last week and it was just a loose ground wire in the outlet box.
