I have a 1963 swing along game. It works fine except for the second player ones was 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 first and second player 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.
Any ideas?
Thanks
Rob

Correction: the jumping wire goes from the 2nd player ones to the 10 points relay.

I put a toggle switch in the jumper wire so i can play one player and gets credits as the game was designed. I switch it back on yo get the second player ones to roll tens when playing 2.
