Video here.. Any ideas? The game is in beautiful condition so I'm hoping it's a common fix.

Can't recall offhand if this has the a/x relay. If so they have to be dead on , can be finicky.

I'm gonna have to see an overall picture to diagnose if the game is, in fact, a wedgehead.

Here you go

Check the ball count unit, doesn't seem to be counting up or down.

That's the unit in the back at the end of video.

Could be a dozen things though, all "common"

I don't own or have schematics for this title, however definitely a wedgehead. The 'F' stepper (AS Relay) in your video is known as a '00 - 90' unit and it's common function is for 'Score matching' at the end of a game.

In some '70's' games this unit was also used for counting the drop target bonus. With the score motor running and the 'F' relay energising as it is, it seems the unit could be part of the drop target circuit. There will be someone who can confirm this from the schematics.

That 'F' relay is for the Match function, or as Gottlieb calls it "00-90 Unit Relay"

From what I can gather.
Check the "A" relay, "Reset Complete Relay". It may not be moving and is stuck. Also, Orange-Red wire contact should be open. There are also a few contacts on the score motor that will need to be checked as well. Contact 2B should be normally open.

I doubt that F steeper has to do with anything. It's moving because the game is trying to reset.

zero switches on score reels are not closed...

Not gonna check out that ball count unit huh?

Ok, I'm out

My Sky Jump does the same thing particularly when the power has been off awhile. Most of the time I just let it do its thing and it fixes itself after about a minute. Other times, I reset the power. I know it's going to be an issue down the road.

Thanks so much all. This is a bit of a long distance thing as I won't be able to see the machine in person for a few weeks, but this will give him some stuff to try out before he drops $$$ on a professional repair. If anyone else has theories, feel free to post them here. I know the video doesn't show a lot but I figured you all could point me in the right direction. I appreciate it! He's excited to get it going and set some high scores with his kid.

Quoted from pinhead52:

That was gonna be my suggestion. The game is trying to zero the scores so it can move on to the next step in the sequence. It doesn't know its there.

Ok thanks to all. This is the owner here. I started a thread this am and have tried a few things. I tried to turn the digits (which were already at zero) to open the points. Then I took an emery board lightly to the contacts. Still no change. I found the ball count wheel (I think is the 1-12 dial in the lower right of the score board) was turned way past 12. I was able to move it back by hand to about #4. Still no change. Then I found in the lower right (while looking in the back of the machine) the ball counter circuit. I moved it to about the third position and it reset when I reset the machine. But relay F still just spins and spins. I'm afraid to just let it go for a few mins thinking it will damage something. I tried to clean the contact points on the F relay with an emery board as well and no change.

I wish I could link these to threads together. Can anyone help. I will post more videos if someone told me what to video and how to post. Lol

Not sure if I should have done this but I did. While it is trying to reset I pulled each score dial out and rotated the dial with my finger a little bit. Each one snapped multiple times. Still no change.
Also while running on the ball counter dial I pushed up on a larger lever on the bottom right corner of it and it seems to activate something on the right front of the machine underneath that makes a big "thud" noise. One time some how the "game over" light light up so I hit the "reset" (middle of the coin door) button. But no change.

You could copy the thread address of the other and post it here directing people to that thread, or vice versa. Good Luck..
