Hi all, I'm a proud enthusiast but not a tech at all. I do not solder...yet. Have a gorgeous working Fireball 1972 and accidentally did something to confuse the game logic: now it pops 2 balls into the shooter lane one right after the other when you lock a ball in either the Odin or the Wotan holes. It will also pop 2 balls into the shooter lane at the beginning of a turn in a multi-player game if there is a ball locked in one of those holes when your turn begins. I think when I cleaned it or otherwise removed the balls from the playfield temporarily I left the machine in a state of expecting a ball somewhere, or a switch un-tripped....and now I have this problem.
Possibly related: I had an earlier issue where a ball would get stuck on its way out to the shooter lane, but it was not predictable or repeatable (the problem I have now is repeatable). It would happen intermittently, every 30 balls or so. I was advised to adjust the leaf switches under the ball ejector. Did I over-do it, and could this be the source of the above? In the old, mis-filed post, chas10e was kind enough to suggest the middle leaf switch staying closed as the culprit. If it is, what then about my stuck ball problem?
