Having trouble with one of my cannon riggers ~15 yrs old. Will auto wind up for about 15 ft, then stop. Have to wait about 20 seconds, then hit the button again, and repeat (up 15 ft, wait 20 seconds...) until it’s up full. Any ideas, or similar experiences? Thinking about taking it apart, checking auto-stop switch, continuity, board, etc.. just looking for a good starting point. Thanks.
