Alright. So, I picked up a Bally Eight Ball a few weeks back. When I bought it, I was told the MPU was flaky (the board looks HIDEOUS) and that I had the option to buy the game with an Alltek. I declined to buy the Alltek. Three weeks later, game went crazy. Some light sockets refused to turn on, a little later, a chime coil stopped working. Did a power cycle - coils started locking on. Game stayed off, Alltek MPU ordered. Even if that's not the issue here - I should have an Ultimate MPU regardless.
Followed the install instructions exactly, checked for 5 on TP1, came in exactly at 5.25 - on the highest acceptable number, but in acceptable range.
Put in the Alltek, the game did indeed start up, but coils still acting odd, bulbs as well.
What's the next troubleshooting step here? Solenoid Driver? I really appreciate any help.
