None of the solenoids or flashers on my Jackbot will fire in test mode. All fuses have been tested/replaced and I just checked them again for continuity, they're all fine. Here are the voltages I just measured, I'm out of my depth on this kind of stuff but two have odd readings:

TP1: 14.73
TP2: 5.04
TP3: 11.85
TP4: jumps to 399 then down to 0.4
TP5: -11.7
TP6: 74.5
TP7: 22.0
TP8: 17.4

I measured TP4 several times and it did this every time, worked its way up to 399 and then settled down to 0.4
TP6 is rather high at 74.5, this should be 50 right?
Machine is an ex-import game if that matters, I assume transformer has been changed back since it was setup in someone's home.
Any help is appreciated!

Okay, I sort of figured out the solenoid prob by accident. When performing the flasher test, I closed the coin door and the flashers started lighting up as they should. Opened coin door, ran solenoid test, and they would each fire ONLY when I closed the coin door. So at least they're working as they should, but now it seems the issue is the high voltage disable switch?

A little more research and I see that nothing is actually wrong, it's a "feature" of the code to disable coils & flashers when the coindoor is open. Who woulda known? Apparently me if I had read the DMD.

Could still use advice/help with the odd voltages above.....anyone?
