For many years I have an EM Bally Little Joe. I cleaned it, put it all back together again, but now I'm stuck with a score motor that keeps on running. I'm not very technical. So I'm looking in this forum for some help in this matter.

When switching on the power, de pinball immediately is settings all score wheels to zero, but then adding a second player, a third player and so on and so on. It won't stop. (normal behaviour: a touch on the left flipper button activates only the illumination).

I'm looking for some help finding the cause of the problem and want to start with identifying the relays that trigger the score motor. So I can check each of them. If another approach is better, please tell me. I'm eager to learn...
I already found out that the startbutton on the front door of the cabinet is not "hanging" or shorted.

Hope someone can help me or point my into the right direction! I can read a little bit the schematics and have one present.
