Usually a PITA or relatively simple? I didn't think you'd see that many, now i'm curious. Usually in the boxes where a DIY'r didn't know what he was doing?
I used a toner when I worked on C-130's...but I rarely needed it, usually we could physically chase the wire. On what I work on now, opens are easy...just gotta make the circuit lol! Shorts...can be anywhere, intermittent are the worst!
@Jds556762 Ever have to chase shorts? I guess residential/commercial shorts just pop a breaker or become catastrophic?
Electronic shorts are a PITA sometimes. Having that kind of morning here lol.
