I hope this is the right place to ask questions about an issue i have with my popeye.
I bought the machine in not quite so working order. I replaced the MPU board with a new rawdog unit because it have battery corrosion issues, i also installed all new caps and bridge rectifiers to the power board to eliminate the random shutoffs that were happening. I have the machine to the point where all solenoid test, and switch tests, including all of the optos are working correctly. However, when i start a game, the trogh kicker simply continues to shoot balls into the trough. Also, even without anything happening, random scores keep appearing on the dmd. Any ideas?

Before i shell out another $70, I also noticed that when i do the switch testing, every switch on the matrix is flickering. Not just the optos, all switches that are shown to be closed. Checking the voltage on all of test points on the power driver board, they all look correct aside from test point one which shows 10v instead of 12v. Could this be the issue? Are all of the switch flickering and possibly causing the random scoring AND the opto issues?

Can i simply remove the connector from J101 and J102 and test the voltage coming direct from the transformer? Do those ever go bad? I ask because that would be the start of the electrical chain to the 12v power i dont have, and i should probably verify the voltage feeding the board first right?
