If I activate either of the mini PF optos they activate as the should but the auto fire and right ramp optos are still dead. I then looked at the auto fire and pulled off a wire that was just hanging on and resoldered it. Same problems.

I decided to disconnect the auto fire plug and the Mini PF switches & right ramp switch work. But when activating either mini pf switches the auto fire switch activates as well.

I then buzzed out the cable that goes to the auto fire and mini pf and found that the mini pf single grey wire beeps on the auto fire grey and black wires. The mini pf black only beeps on the auto fire black. I couldn't see anything obvious and so cut the grey wire, plugged in the new clock pcb and got "SLAM TILT" error. I didn't try with the old clock pcb before reconnecting the wire 

Hope this isn't too confusing for someone to see something abvious. Help would be greatly appreciated.
