I've got a pesky problem with a switch firing on IMDN - for example as the ball is ejected from the trough into the shooter lane it often but not always fires, so that you start the game with a number of points, not zero points, and the option to choose a song disappears because the machine thinks the ball is already in play. But I can't identify which one it is. It's not the slingshot switches as I have put slips of paper between the leaves to rule them out. Is there a way of seeing what switches have fired in the switch tests, or some other clever way of figuring out which one is sometimes firing when its not meant to
