This unit in the back box thats numbered 0-37 and has a little square hole that you can see one number at a time from the front glass, it never moves are does anything but this old Williams em game apears tp play ok without it, evidently not.
So whats the set up for this or a test for it. Ive never seen it change numbers the first time but the game goes from player 1 to player 2 perfect it seems and the score reels count every point. I have the schematic but it could take me a week to figure it out if not longer. This unit has been cleaned and nothing is froze up, and both coils work, i
m not aware that either coil has fired, I manually checked them with a proper voltage supply.
Thankyou.
