Was chasing a fault on a 76 Gottlieb machine...
sometimes the ball wont eject for game play.
Went through the schematics as you do.. and its the usual sequence.. AX relay.... 1C on score motor... blah blah... and also 15th position on bonus stepper.
15th position still exists... but not a lot else... dont think even Moses could have parted these better...
Suggestions anyone?... id like to repair rather than replace
