Try all the easy stuff, then if necessary, get another MF unit to swap in to verify the diagnosis.
Unfortunately you are spot on. I swapped out the MF unit and everything works fine. What sucks is everything else works perfect on the bad board, I just get a constant slow recoil. I guess I could hold her for another project where I will not be using recoil....
