Going to do some more troubleshooting tonight thanks for the suggestions guys. I know when I first got it that they had the flipper relay jammed in and the game played fine. So the coils do work fine. The SDB is a known working board so all the components should be fine. I must have something wrong with a connector or possibly in the U11 chip. I'll post more when I do some more testing. So close but yet so far away haha..
