The problem I am having is Xenon seems to not know that it has already sent a ball to the plunger. As soon as one ball is by the plunger and there is still one in the drain, it will replay the intro "Welcome to Xenon" or whatever it says, and launch the second ball. I can manually take one of the balls and put it back in the drain, and it will repeat the above procedure. All of the switches test good, as do the diodes. Any thoughts?
