Overheard a lead tech say "if you can't troubleshoot a bad crimp in under 10 minutes, you shouldn't be touching the plane"...
That hit me after I spent 15 minutes yesterday chasing a bad ground on a G1000 install, has anyone else found a quick trick for isolating intermittent crimp failures?

... yeah and I bet that lead tech has never sat there for 20 minutes with a multimeter jabbing at a connector that works fine til you put pressure on the wire lol. My trick is I just wiggle the harness with one hand while watching the resistance on the meter, but half the time it's a hairline break inside the insulation so you gotta bend every single wire like a noodle til the reading jumps. Also pro tip if you smell burnt plastic right away you're already way past 10 minutes.

Wiggling every single wire like a noodle? That just gave me a flashback to a badly corroded trailer harness I fought with for almost an hour last fall. You'd bend one wire and nothing, bend another and the meter would flicker for half a second, then go dead again. Finally found a broken strand hidden right inside a rubber grommet where you couldn't even see it without peeling the insulation back. And that smell - once you get that burnt plastic smell in your nose it stays with you the rest of the day.
