I just picked up a Genie and have a few little issues I could use some help with. First off the right upper flipper is pretty weak I looked at the coils on both upper flippers and the weak one looks like a new A-17875 just like the lower flippers but the strong left flipper has a a-5141. Do I need two new coils or just one and if so what coils should be there. I also have 3 new a-20095's and trying to decide if I should use those for the lower flippers. Last problem is the only noise it makes is the na, naaa, na , naaa, naaa. Not really sure how to describe it other then that but if I hit the sound test switch it plays all other sounds, and some times it will play the sound when I hit the flippers. Is it possible there a switch some where that is supposed to make that noise that could be touching or gaped to close?
