I just picked up an Eight Ball Deluxe. Overall it's pretty nice, but the 1x 2x 3x 4x drop targets intermittently dont reset. Also the 2 ball drop target drop solenoid does work when this happens. I understand that they are on the same circuit on the Solenoid driver board. I've checked and cleaned all the connections on the Solenoid Driver Board and the solenoid expander board and re-soldered the pins as well. The light and relay on the expander board seem to work fine so I'm guessing that's not the issue.
Just when I think I have it working fine it comes back. Any ideas?
