When I turned the machine on MPU shows green lights flashing and goes through its steps 2 flashes and then 7 more? After that it does weird things now. I have checked and replaced all the fuses (6). I have tested each solenoid and they fire. The issue is the solenoid or I believe it is called the knocker goes off numerous times and then half the solenoids do not work once the games starts. I have tested the Solenoid driver resistors. I see no wires loose. Does any one know what would cause this issue? It just started a few days ago. Been working great. I put it in solenoid test mode and 7,8,10,11 do not fire. I jumper them to ground on the non power side and they all fire.. Any help would be appreciated.
Thank you,
Tim
