I have a 1963 swing along game. It works fine except for the second player ones were not rolling to the tens and there were random credits. The first player didnt have any issues.
I had a tech in and he ran a wire between the second player ones and the tens coil and that fixed the second player roll to tens issue. But now both players will issue random credits.
This is even with all the high score pins out and the matching pins unplugged. I put a toggle switch in the wire the tech ran so I can play one player games and they work fine. But whenever i play two players the game awards credits randomly.
Any ideas?
Thanks
Rob

When you hit 26 credits it stops issuing credits. I will send pics of back when i get a chance.

I had to take in several pics. Hope you can work with it.
Thanks

Ill try to see if i can determine what scores award credits. Also its provides credits in the lower ranges so the 1000 points light has not come on yet. And it seams like once it hits the first credit almost everything it his provides another for about 5 credits.

O and P look ok.
Not sure how to check resistance.
Cleaned the ball count unit with 600 grit sand paper then alcohol.
No change.
Watched O and P while credits were awarded. Didn’t see anything.
Credits are awarded at random. Can’t predict. I have had 0,1,5,7 and 9 just now. When credits start being awarded an additional credit is awarded if the score increases by 10 as long as the ones don’t change. This goes until 26 credits where it stops.

Dave, THANK YOU!!!
That solved the issue. Now everything works on my machine except the match and i can live with that.
I took a picture of the unsoldered wire showing the position should anyone else have the same issue. The colors can be hard to determine.
Thanks again
Rob
