Vent: Chased a ground fault for 6 hours on a King Air 200

Worked a King Air 200 last Tuesday. Pilot said the nav lights were flickering. Thought it would be a quick fix. Checked every bulb, every connector, every breaker. Nothing. Spent the whole afternoon tracing wires in the tail cone. Finally found it at 5 PM. A single chafed wire behind a panel near the aft equipment bay. Barely visible. Took me 6 hours total. All for a 10 minute fix once I saw it. Anyone else spend way too long on something that should have been obvious?

Man that is the worst kind of find. I read somewhere that chafed wires in the tail are super common on King Airs because of all the vibration back there. Six hours is brutal but at least you saved the next guy some trouble.

Vibration might not be the real culprit though, more likely just poor routing from the factory.
