The ball return solenoid isn't firing on my blackout - it had burned to a crisp. I put a new one in, still no luck.
The transistor for the original board would be Q15 but there isn't one of those on the Rottendog MPU327-3. But on the Rottendog MPU327 board, Q13 tests .2 where all other transistors test .5 - I think this is an indication of a bad transistor, yes?
Is there anything else I should replace besides that one transistor?

Search for testing transistors.

Thanks for that, it's great reading.
Do you think the diode could have blown on the new coil, too? I did switch the power on and try to start a game with the new coil in.
