Hopefully someone can help me out. I have a Quick Draw that was working ok and then I switched it from 5 balls to 3 and now the bonus doesn't subtract and add to the score unit the way it should. I resoldered the connections to the brass fingers on the step unit as one of them had come desoldered from the finger. I don't have any images to look at to be certain the wiring on the bakelite side of the board is correct so I'm uncertain if it's in the correct location to me they appear to be wired in series, jumping from on to the next.
Could use a hand if someone might know where to look. I can read schematics somewhat but not great at following the switch logic yet.
