    Hello out there I am in need of a score motor schematic for a 76 Bally old Chicago
    I have 8 cut wires and 8 switch lugs but no clue what goes where.
    I have all the other Schematics but the score motor.
    Thanks for any help caleb.

    Some Bally games have non used switches and wires not connected.. Hokus Pokus is one.

    There is no schematic for a score motor itself. You'll have to go through the schematic for the game and find which switches are missing the wire, find that switch on the schematic, and then you'll find the wire color that belongs to that switch.

    Bally score motors go by each cam, such as 1, 2, 3 etc, and then the levels are the number of switches on each cog, with A as the lowest switch. So, for example, 7C would be the third switch up from the bottom on the 7th cam.

    Bally schematics use number combinations for the wire colors. Fortunately there is a key for that on the schematic.

    There is no remnant of the wire on any of the lugs that are missing wires? Yikes. Someone wanted to cause a problem for sure.

    On a score motor? I've never seen a switch on a score motor with no wiring attached, no matter who the manufacturer was. That would certainly be odd to say the least.

    I believe I've seen this same thing. Also, I believe there are some other threads showing same thing as correct, but don't quote me on that.

    Diagnose each (If any) problem with the machine using the full game schematic diagram and standard electrical troubleshooting techniques. When working on a circuit that shows a score motor switch (circled), hone in on that looking at the hanging wires.
    But keep in mind Bally pins of that era had unused wires depending on destination.

    German exports used a few of those wires.

    In response first thanks to all.
    What started me on the hunt was the multiplayer does not work. If you hand trip everything each part will work.
    But if you add more then 1 player you have unlimited balls and it will stay on player one. All coils and switches are good steppers are clean and smooth.

    There is one switch out of the 8 that had a wire at one time. The other 7 look brand new

    Bally Hokus Pokus, Flicker ( I just woeked on one) and Bally Monte Carlo. I am sure there are more. And when you see them , you automatically think thats whete they go.

    Didn't see that on mine but I didn't do a wire-by-wire inspection; rather I did the troubleshoot the game until everything works method. Got me curious enough that I'm going to take a close look-over in the next day or so.

    You find unused clipped wire in several location on Bally pins of that era. I would guess they saved money by using the same wiring harness in multiple pins. My Old Chicago is the same.

    If you have one specific switch you think a wire came off of, maybe try posting a clear pic of that one. That way there is a better chance someone else with same machine can verify and tell you what color wire (if any) is attached on theirs.

    May be worth a shot.
