I have a 1963 Swing Along machine. It was working fine but now it is stuck counting by ones and/or tens. I lave to trip relay labeled R to get it to hum and then when i hit the play button it resets and starts counting by ones or tens. If i unplug the playing surface it will just reset so i think a something is stuck. I can’t find any issues every thing i check seems to be ok. Any suggestions???

I tried removing the rubber rings and the counting continued.

Switches behind rings and spinners look ok.

Like the paper idea. But unfortunately the scoring continued. Thin maybe the bumpers?

Put paper on the normally open arms of the bumpers , no change.

If I unplug either harness connector the machine will start with no counting. So I believe something in the playing board has to be the issue. Do you agreed?

I really appreciate your help. I will continue the process of elimination on Thursday when i am off. If I can’t find the issue I will try unsoldering the power to one side of each component.

One more thing, i am running these checks with the playing field sitting on the locking bar as opposed to be locked in. That should not make any difference, correct?

I was trying to find a glitch where the 2nd player would be awarded free games at low totals randomly, but that was basically changing the pins on the free game score.
Then my machine wouldn’t stop running, not sure why so I unplugged it. Same thing happened to me the other day and i just checked the movement of the solenoids in the bottom of the cabinet and it work fine until today.

Well said!

I finally found it. On the push down wire left side just above the flipper.
Thanks for your help!!!!!
Is there a standard height for front to back for the angle of the table

Better asked, what should the slope of the playing surface be?

Thanks again! I really appreciate your help and this site is great!!!!!

New issue- the bumper score 1 point when hit before they are lit, as they should. But when they are lit, they still work sut don’t scoe any points.
