Spent all morning tracing a single wire in a vintage cockpit

You know how it is with older birds, the wiring diagrams are more like suggestions sometimes. I was helping a buddy with his restoration project, a classic from the 70s, and the comms were totally dead. No static, no power, nothing. We had to pull up half the floor panels just to follow one line from the radio stack back to the power bus. It felt like forever, just lying on my back with a flashlight, inch by inch. Turns out it was rubbed through where it passed behind a support bracket, totally hidden. A little heat shrink and some fresh tie wraps later, and we had clear audio. Such a simple fix, but finding it was the real win. Felt pretty good to hear that first crackle come through the headset.

Heard mechanics say that all the time, lol.

In Marana, a corroded antenna cable ate up our whole Saturday before we found it.

Wiring diagrams are more like suggestions" is the truest thing I've ever heard. I've spent whole days chasing a short that turned out to be a single strand of wire touching a bolt head. One time I replaced an entire harness section only to find the problem was a 50 cent fuse I checked twice. Makes you feel real smart.
