I recently acquired a 1953 United chief shuffle alley. Originally when I got it I was told it worked. Upon starting it up I realized that was not the case. Upon initial start up the scout motor was continually spinning and attempting to reset the machine to initial state. Through searching the sight I found that one of the leaf switches on the score motor would not connect. Once adjust the machine appears to set up to play.

I now have no response from the playing field at all. Thanks again to this site I was able to get a hi res photo of the wiring diagram. Through so investigator I decided to start at the beginning with trouble shooting. So I know it is said that the transformers don’t go bad but mine appears to not give the proper voltage Upon exiting the transformer. I have 120v on the input, but am not getting 30v or 6v at the other terminals. Could there be another cause other than the transformer being bad? On a multi meter I see like 1 to 1.5 volts ac on those terminals. I am very new to em machines so any help is appreciated

Score motor not scout motor, sorry

Bump. So I decided to remove the transformer to test while removed from the circuit. If I still can not get Voltage out of the 6v or 3v pins. I am really hoping someone can help. I attached a Diagram of the pins, can someone explain how to test? I also attached a clip of the electrical diagram, can someone explain what Voltage the Yellow wire on the output of the transformer would be? or if it is a neutral?

I tested it by putting Neutral wire to "Normal Voltage Line"and Hot Wire to purple tab. With this setup I have 0 Volts output.

Please help.
