Just realized my old trick for tracing a wire bundle in a Cessna 172 saved a 3-hour job in Boise

I was troubleshooting a nav light issue in a cramped panel, and instead of pulling the whole bundle, I used a fiber optic camera from my inspection kit to follow the single wire back to a corroded pin at the firewall connector.

That's the kind of trick that makes you feel like a wizard. Bet the guy who designed that wire bundle never thought someone would send a tiny camera through it. Saved yourself a whole afternoon of swearing at plastic clips and skinned knuckles. Always nice when the fancy tool actually does the job you bought it for.

Waste a whole afternoon? Nah, that's where you learn the car. Those plastic clips have a feel to them, a specific sound when they let go. You miss all that with a camera on a stick. Sure, the fancy tool works, but you also lose the chance to spot the cracked hose or the loose ground wire right next to it. Sometimes the slow way shows you more.
