Quoted from AdjustFailure:

My Evel Knievel has had this problem for years - if you "nail" the center stand up target with a hard direct hit, the ball bounces off but does not register a hit. However if it is hit by the ball a bit less directly, a bit softer or at an angle, it always registers the hit with chimes and scoring. I have cleaned and adjusted the switch behind the target but still no change. I am now thinking it is something else, on the boards or the electronics that are the problem. Anyone have any ideas how to diagnose where the problem is that prevents recognizing a fast/hard/direct hit ?

Thanks for the advice -- just to ensure I understand you -- which one is ceramic ? The green one ? The one in the machine I will remove and install the green one but across the switch contacts not the diode contacts if I understand correctly (assuming the green one is a good replacement and polarity is a non-issue?)
Sorry for asking such basic questions, I have not worked with capacitors much before and don't want to screw things up.
