I’m having some trouble with an Old Chicago and have a suspicion that it might be related to the ball count unit.

Could somebody with a properly functioning Old Chicago please post a photo of the ball count unit disk/spider in the home position? I need to visually verify that mine is assembled correctly.

I don't have Old Chicago anymore, but if you post a pic of your ball count unit I could probably tell you if it's assembled correctly. And when you say "home position" do you mean reset to ball number 1?

Yes, I’m calling the ball 1 position “home”. I’m specifically trying to figure out if everything is in the correct position on the disk and gear stepper.

Thank you. Comparing our photos, it looks like mine is set up the same as yours. When you manually step up your back count unit, how many clicks do you get? I get six. It seems like I should only get 5, right? Another question I have now is on the gear side, when the unit is in the home (ball 1) position, is the pawl engaged with a tooth or hovering above the teeth? Mine hovers above the teeth, not engaging until that first actuation of the plunger.

It looks like my spring for the pawl is not original and maybe too tight?

I believe you need 6 clicks one for end of game.

Thanks. I was thinking 5 clicks for five balls. I didn’t think about needing another step to reach the game over circuit.

Clean your rivets and spider rivets. See what happens. I have had several Bally games that count extra balls or do not go to game over simply because of dirty contacts.

Good idea. I’ll give that a shot. Can’t hurt.
