the advice re: type of lube is salient, but don't discount the possibility of failed springs

You do say you replaced the springs

What you describe, though, sounds like the pawls aren't catching correctly

There is, at least for Harken, a particular way to install the springs

There is also the possibility that the pawl pockets are worn, or the pawls themselves worn
