Did the problem happen suddenly or did you receive the game in this condition?

Have you verified all the other coils and switches work properly in diagnostics?

I second this - What happens when you highlight the visor motor (test #13) during the coil test? Does it do the same thing?

I had this problem or something like it years ago. I attributed it to a problem motor. I put a capacitor across the connector and that seem to solve the issue for me. It was a large disc cap that I used. It may have been 1uf or .1 I really don’t remember. The game was sold shortly after the repair so I don’t know if it was reliable over time. I’m not sure if there supposed to be one there. Mine didn’t have one. If you do then I suggest replacing it.

Under the playfield the motor has a molex connector. You could experiment with a cap across there pretty easy without modifying anything. Use caution if you try an electrolytic cap. Polarity is important if it’s a dc motor. I think it’s an ac motor but don’t remember.

Good luck
