I am working on a little board that is part of a big coin op redemption
piece. It has 5 IC's 12 TIP22 transistors a bunch of caps on the IC's.
another transistor and two other electrolytic. There are five of these
boards. All exact duplicates. So I thought that this would be a good time
for a Huntron. But no matter what I do I can't seem to isolate the problem.
It seems where ever the fault is it influences the whole board. Is there a
technique or tool I can use to figure out where the problem is? I can't
apply power because it needs the whole setup to run and it is far away in a
crowed busy place. Any helpful ideas out there for me.
Thanks
Russ
