I have been able to apply power manually to the tilt lock motor and watch the lever go back and forth. I also verified that the D shaped shafts that turns the potentiometer turns about 3/4 turn in each direction.
I can't actually engage the tilt lock manually because the tilt lock motor junction (behind the little plastic cover) is busted.
Also, does the manual screw on the back of the tilt motor adjust the potentiometer shaft? I'll be able to figure this out when I disassemble the bad tilt motor assy.
last question. ... does the cable that comes from the tilt motor to the front micro switch actually do more than that. For example; does it hook up to the brake pads that lock the tilt?
