Why is this happening?  The movement was just restored!  Do the contacts need cleaning already? Every SWCC owner asks that question eventually.  It turns out that it is normal.  Consider the sequence that occurs at winding: 1.  Cam lifts hourly contact and just touches mating finger contact 2.  Vibration from motor causes cam to back […]
