I have had a problem when the motor was stowed it would not go to deploy on the controller, it would stay on stow. I was looking around the bottom of the mounting base on the motor and moved a part that is spring loaded and it moved forward. I then had a deploy indication on my controller. I looked at a parts schematic and I believe the part is:Cam, Pin sensor W/magnet. #618.
I have not seen anyone talk about this on any of the forums.
