I'm working on a Gottlib Egg Head an am having a start up issue. Sometimes it will start and then sometimes it won't. It gets hung up when the SR relay won't activate. If I activate it by hand the game runs fine. About every other time it starts fine and plays so I know the relay works and must be a dirty/ misadjusted switch. When I go to the schematics I find the score motor 4c NO and the DB NC. Which switch on the DB (reset relay) is responsible? I'm starting to get the hang of reading schematics but still have a little learning to go

Check the switch stack that is actuated by the ball gate. One of the switches on this stack needs to be closed when the gate is down (blocking the ball trough) in order to enable the replay button on the front door. These switches often get knocked out of whack by accident when the playfield is raised or lowered.

Hey all I am having a issue with startup too. Plug machine in and hit coin switch then machine attempts to start up but the display gets stuck on 900 and it just loops continually trying to reset the 9 to zero. Nothing in upper display making sound when it comes to the 9s turn. Don't have schematics, looking for those too. Thank you.
