Judge Dredd
Bally, 1993Guys,
Just picked up a JD. Fixed a couple issues, but not sure where to start on this one. During game play, when a solenoid activates, the game scores points like the ball went up the middle ramp. At first, it's not every solenoid. But as the game progresses, it becomes every one.
Thoughts? Thanks in advance.

Could be vibration or electrical. Although electrical is less likely since it's only affecting one opto.
Clean the optos with alcohol and check the alignment and that everything is firmly mounted. Reflow the solder on the optos and check any connectors. Check and make sure you've got a good solid 12 volts at the opto when the solenoids are being fired.
