Watching new guys skip the continuity check on a simple wire run

I saw a kid fresh out of school at the hangar last week. He was replacing a nav light wire and went straight to power after the splice. No meter, no tone, nothing. That used to be the first thing you learned, back when we had actual paper manuals for a 737-200. I've seen it cause a 3 hour delay on a C-check because a pinched wire took out a whole bus. My old boss in Wichita would have you redo the whole run if you missed that step. What's the one basic habit you see people forget now?

Remember that guy who fried the APU start relay? My buddy was on that crew. They had to pull the whole panel to find the melted wire.

Grab your meter before you even strip the wire. It takes two seconds to check for a short to ground or power before you fire it up. That habit saved me from blowing a circuit breaker on a flap motor last year. Skipping it just makes more work for everyone when the system won't come online.
