Spent 45 minutes chasing a ghost on a King Air 200 in Tulsa last Thursday

I was working on a King Air 200 at Riverside Airport in Tulsa and the right side NAV display kept flickering. Pulled the panel, reseated all the connectors, checked the wiring diagram twice, and still nothing. Finally noticed a tiny crack in a solder joint on the back of the display connector that only showed up when I flexed the harness. One quick reflow job and it's been solid ever since. Anyone else run into weird intermittent issues that just turn out to be a cold joint hiding in plain sight?

Hate those sneaky cracks. Drove me nuts once too.

@the_logan what did yours end up being from? Was it just a bad install or did the house settle weird over time? I've seen both cause those things and its never a fun surprise. Mine turned out to be a cracked floor joist that took forever to find because it was behind the drywall. Still makes me mad thinking about how long we had to deal with that popping sound every time someone walked across the room.

Man I feel your pain. Found mine under the subfloor after chasing it forever.
