I’m in about the same spot with my CT. I did supply power directly to the Z relay and it tripped and closed the doors. I’m still working on this but speculate one of the reel switches is not closed even though it is at zero. Score motor is not turning in my case. Let me know how things go and I’ll do the same here. Good luck!

Have you made sure all the zero switches are closed? Checked all of mine and adjusted as necessary. Mine will now finish the start sequence (open and close doors, release ball gate after points are scored) once the reels show zeros. However it still struggles to get the reels to zeros so I’ll work on that next. Score motor runs properly.
