Well Rob
Not sure if beeing 4 player makes any difference but
on 0 all switches are open
on 9 all switches are closed
on 1-8 all switches are closed except the center switch
Four players may be different does anyone have a single player Gottlieb they can check?
Hmmm this is different to what Mick has said but i adjusted and cleaned the contacts to reflect what you said Daniel and now im just getting the motor running without resetting any score reels.
