I'm having issues with my upper flipper and was wondering if it could be a hardware or software issue. I'm running 0.90 on my LE and notice that the upper flipper only works about half of the time. Would there be software code that prevents the upper flipper from functioning at times? Or would this be a hardware issue? I checked the wire connections and they look good, and it does work periodically. Does anyone else have this issue? Any ideas of what to look at?
