I finally realized why that old Otis mechanic kept squinting at my work
Had a retired union guy from the 70s watch me swap a door lock controller last Tuesday and he said I was moving too fast with my meter, and it hit me that I've been skipping the basic step of reading voltage under load instead of just checking continuity, the way he showed me saved me 30 minutes on the next call - has anyone else had an old timer change how they troubleshoot?

Did you check for voltage drop before or after explaining how old paper maps work?

The voltage drop check happened right after I finished explaining how my granddad used to fold road maps wrong for 40 years. I tested it on a 12v circuit in my truck and got a 0.8v drop that I definitely created by accident while fiddling with the multimeter leads. Pretty sure I shorted something out for a second because the dome light flickered and I smelled that weird electrical burning smell for a second. So to answer your question, the maps came first and the voltage check was a total hack job that proved nothing except I should probably stick to paper directions. I'm a disaster with electrical stuff but at least I can find my way home with a folded map.

Ha, I used to think electrical was simple until I fried a wire. Thanks @perry.jesse for the reality check.
