dipasqut you mentioned you reattached the motor wire. Did you re-attach both red and black? Is it possible you attached them backwards? I got similar CW/CCW errors when I attached the red wire to the red dot side of a new motor. Once I switched sides of the wires on the motor, my errors went away. The next question is, where did you buy your Optos? Many here have had issues with Optos bought at Marcos. Esp. for the 5 Opto mushroom targets. In the video, I saw an error for Opto #74, which is in the 5 opto bank of mushrooms. Also, I saw in the video how in test that the MPF levels are off. This also speaks to the beam being broken by the cam at the wrong time. Which is either that your cam has slipped on the shaft of the motor/gear box or you are running reverse polarity to the motor. I have also had the speaker wires grab my wires after a repair and can relate. I have included 3 pictures of the wiring to the motor and Optos. You can see in the last picture how the Optos shoot a beam across when the cam has an opening.
