Why does everyone skip the basic continuity test? | Avionics Technicians

Most techs rely on digital tools, but I fixed a transponder glitch with a simple multimeter check. It was a small win that reminded me of the basics.

Had a similar thing last week where a whole rack was acting up, turned out to be a single loose connector (the kind you'd miss if you went straight for the diagnostics software). Felt pretty good to spot it.

Found a bent pin once, saved me hours of troubleshooting.

That story from violaa29 about the loose connector is a good find for sure. But honestly, how often does that actually happen? It feels like people only post the big "aha" moments online, not the hundred times they plugged in the diagnostic tool first and it was fine. Most folks probably do the simple check and just move on without making a post about it.

But the basics catch what software misses.
