Warning: the old timer who told me to always test the line before crimping was dead right
Six months back a retired tech named Gus told me on a job in Gary to always tone out the line before I put a connector on, no matter how sure I was. I nodded and mostly ignored it, because who has time for that on a Friday with 4 more installs lined up. Well, on Tuesday I spent 90 minutes chasing a dead signal at a duplex, swapped two splitters, and it turned out the line was never live from the pedestal. Gus's trick would have caught it in 30 seconds with the toner. I'm not saying I'm a believer in every tip some old guy hands out, but this one cost me a lunch break and a lot of pride. What's the one piece of advice from a veteran that keeps paying off for you?
