I agree with this. In the case of #1, you can perform a continuity check on the cable with an ohm or multi-meter. You can also put the multi meter on the plug of the potentiometer and spin the wind vane. If the resistance reading is "open" or "infinite" or it doesn't change at all when rotating the wind vane, then the problem is there.
I have an ancient (broken) Signet knotmeter, and found that they were still in business. Definitely check out their website. They offer drop-in replacements for some of their instruments.
