Hi, thanks for any help you can give me!!! New owner of a bally all star deluxe bowler. I have two questions on how it works. Game plays great but will not give me a strike or spare. If I knock down all the pins on the first ball, it will still give me a second ball with nothing to shoot at. After the second ball with nothing to shoot at, it will score me 10 pins like they all went down but no strike. Same if it takes me two balls to get all the pins down. No strike or spare awarded, but scores me ten pins. Same for both players. Both steppers for strikes and spares work fine. Thanks for any help you can give me!!! Brian.
Steve at pinball resource has the schematic if you don't already have one. That is the best way to trace down problems like this. Could be in several locations. Any switches in the circuits that aren't making good contact for one. Also, the large steppers have multiple spider arms that sometimes may not make good contact with the rivets. I worked on one a few years ago and found those kinds of issues. Check all 10 pins to make sure that they register when they flip up. Great game! Enjoy.
