Well after moving all my games out of Illinois I have finally set them all up.
I have minor issues with Shadow and F-14. (I'll make a separate post for F14)
My Shadow has a lower right dead flipper. The other three and the rest of the game works 100%.
I have looked at the wiring and do not see any noticeable issues.
The right button and assembly look fine as well.
I am new to working on pins and looking for guidance as to what to try or look for next.
