So I'm working on this mod, and I like to check continuity along the way (instead of all at once at the end) because there's a lot of steps. I don't know a ton about electronics (as this thread will make clear), but I know enough to (usually) successfully complete some little projects like this.
The issue is, on this one resistor, I'm not getting continuity on one side of it.
On the attached schematic, it's R7 (150 ohm). I'm getting continuity on the one leg that's going to R34, but on the end that's going to the transistors (Q10 and Q11), I'm not.
It wasn't until I took this picture that I noticed what appears to be a severed trace. I had looked under a magnifying glass at it, but I guess the light wasn't right or something. This morning when I took the picture (for this post), I noticed it (see photo).
If it is indeed a lifted trace, I have no problem making a jumper. Before I do that, though, I just wanted to double check that there's nothing special about checking continuity with transistors. In other words, I should be able to get continuity from the point A (top leg of R7) to point B (transistor), even without current running through the circuit, correct?
I know this is probably a really stupid question, but before I noticed that issue with the lifted trace in the photo, I couldn't tell if that actually was a trace or if it was just maybe a scratch. In the photo, it's much clearer that it almost certainly is a trace that's been severed.
Thanks!
