I had a Centaur a long time ago but it had a weird glitch where during the multiball shooter launches, sometimes it would get confused and shoot one more ball than it was supposed to and it always bugged me. Tried fooling with the switch in the launch lane, the actuator wire to lengthen the closure, using a new switch, nothing fixed it. Still had the problem years later when I sold it. Now I wonder if it maybe it was the capacitor on the switch but can't remember if it even had one or anything about that. This was before the internet when you could get easier help. Only time I simply gave up on a problem. I still wish I had figured that one out!
