Also, this thread might help. I had this issue for a few months when I first acquired mine. For me it actually turned out to be a misadjusted switch up in the backbox on the no match unit in the middle at the top I believe... even when dirty it wouldn't alternate (got stuck on gear dirt) and it attracts dust. Good luck as this game is just awesome. https://pinside.com/pinball/forum/topic/small-issue-with-williams-gran-prix

Sure! Each hit advances that nylon gear 1 position, that action opens and closes this switch, which alternates the left to right bonus lights.
