Had a nav system on a King Air 200 in Boise just start spitting out random altitude data during pre-flight.
Everything checked fine on the ground, but the second we powered up for taxi, the HSI started showing us at 15,000 feet while we were still on the tarmac. Tore into the wiring behind the panel, found a single pin in the connector for the ADC was backed out maybe a millimeter. Must have been just enough to make intermittent contact. Took all of ten seconds to reseat it, but it ate up an hour of troubleshooting time. What's the weirdest 'simple' fault you've chased that turned out to be something stupid like that?

That "single pin backed out" is the worst kind of find.

Ugh, that reminds me of the time my whole drawer fell apart.
