When the power assist handle is engaged left or right. motor kicks in, chain moves the direction I move the handle BUT the II assly won't move easily (no power assist) I have to push reaaal hard to move the assly in either direction. I know switch is good, I know motor is good, chain is tight (I think) because it moves. WHY isn't the power assist helping?
has to be a mechanical issue, I can't find power assist drive assly drwaing. any help is appreciated.
