I'm working on a Skylab pin for a friend of mine. The last (known) problem I have is that the game awards a double bonus on every ball - not just the last ball. I can't figure out why.
The ball count unit seems to be working fine - as does the Spacelab advance / step down unit. I've examined every relay that appears to be relevant, and they all look OK. I can't see anything obviously wrong with the score motor. The timing of the switch stacks / cams appears to be right. And, if I look through the coin door during "game play", I can see that the double bonus relay only activates on the last ball (as it should). And yet, the game still awards a double bonus on every ball - not just the last ball. Any thoughts on why this might be?
Thanks in advance for any help
