Something else I notice... When I manually turn the adjuster to raise the light up the light would jerk back down to the mid height point at which it stops when I try to let the lights down.
Its like the motor has some sort of memory telling it that it is supposed to be down. However, when I twist it really fast while slightly pulling up on the light and it comes up to full height with no problem. Then, when I send the lights down it stops halfway down or maybe a little higher up than half way.
I am beginning to think that nothing is in the way; especially since I cannot see anything and nothing has changed since when it started doing this. Could it be that the motor has a glitch or is confused into thinking that midway down is the bottom?
Is there some sort of adjustment to how far up the come and how far down they go when turned up and down?
