Hello all. I am very new to this so please take it easy on me. I picked up 2 machines from someone a while back and im just getting around to working on them. I have a Stern Stars which i got working recently with the help of a local pinball repairman but id like to get the future spa working on my own. I had to purchase the Alltek MPU board. I got that in and replaced almost all of the connectors ( im waiting on a shipment to complete the rest). The machine turns on. I can put a quarter in and start a game. And in test mode all but 3 Coils fire. But when i play none of the coils work (they will not fire or register any points). I am very new at this and i have some basic understanding of electronics but i cant seem to figure it out. Any help or suggestions would be appreciated. Ive already checked all of my fuses and the ohms of each coil. Thanks!
