I am by far a expert and have been lucky to have a patient friend who has been fixing machines along time who hags taught me a lot. Anyway here is what I've learned so far. In adjusting switches make sure there is movement when switch opens or closes. Just because they touch doesn't mean there making good contact. Take a buis card and fold then run them between switches. I'm still learning sch but don't over think it.go from start switch and just go to next relay then follow to next on sch. I know it gets confusing but it's not hard it's just time consuming. I hope this helps.im sure your game is a simple fix. Good luck
