It is mechanical. It is possible something has come apart or is stuck. I haven't had mine apart yet so I am going to be little help on this other than it being a mechanical screw link. Clockwise is down and counter clockwise is up. There are a lot of turns and it stops at the end of movement.I tried to adjust the headlight but it doesn't move. Is it an electric adjuster or mechanical? Any ideas what I can do to get it working?
