Hey everyone! I'm working on a Bally Wizard and none of the score reels are moving. When starting up a game, the scores will not reset to zero, but if I manually activate the score reset relays in the backbox, the scores will activate just fine. So something lower in the cabinet is messed up and not sending any signal to the backbox. Once I have manually reset the score reels to zero, I am able to play a game, just no scores ever activate. I have the schematics here and I'm trying to get better at learning to read them. I am thinking it has something to do with the G15 area. Any help would be appreciated.

If none of the score reels reset during the reset process, then most likely there is a connection problem between main cabinet and the backbox. Try cleaning up the Jones plug connections in the backbox. I usually use 400 grit sandpaper to clean up the plugs. Sometimes the plugs have a white chalky residue and this causes connection issues.

If the Jones plug connections are good, and the score reels still don't reset when starting a game normally, then there's a problem with one of the score motor switches (2A, 8D, 11B), or with a reset relay switch.

Also check the reset relay. Here is part of the schematic.
