I have a VP1, but the anemometer assembly is pretty much the same.

From the Davis manual for the Anemometer (Weather Wizard III) it says

Wind speed reads 0 all the time or intermittently
• Make sure anemometer cable is plugged into the jack marked WIND on the
junction box.
• Check for broken wire along length of anemometer cable. Carefully check
areas where the cable has been secured.
• Try dropping the wind cups approximately 1/16” to 1/8” (1.5 to 3 mm) lower
on the mounting shaft. Use the included Allen wrench to loosen and retighten
the wind cup assembly.
• If you still do not get a reading, the problem is probably with the anemometer.
Contact Davis Technical Support for return authorization.

as the only troubleshooting suggested for zero wind-speed.  I'd suggest you contact Davis at their 800 number.

I hope you've made ready for the approaching storm and all fares well with you!

Best regards,
Ken

If it comes down to a bad reed switch in the anemometer, tapping on the mast with a hammer while the wind is blowing might bring it back to operation temporarily for a few minutes or days.

As you have learned, electrical tape by itself is not a reliable way to waterproof a connection. Depending on your needs, you could use "liquid electrical tape", Plasti-Dip, linerless rubber electrical tape, or a really thick sticky rubbery tape like Vapo-Wrap or 3M Scotch 06147 Vinyl Mastic Moisture Seal Tape.

In any case, put a layer of good quality electrical tape like Scotch 33+ over anything else. Outdoor weatherproofing is not the place to use cheapo drugstore electrical tape.

A really watertight (but non-removable) splice enclosure can be made from an enclosure like a pill bottle or 35mm film can. Run the cable through the bottom, put the splice inside, and then pot it with 5 minute epoxy or maybe RTV silicone.

Another way to waterproof individual wire splices is to use silicone gel-filled phone splices, like THESE from Rat Shack. These are what Davis sends when you need to replace your anemometer/wind vane. Note: Unless you really only need 4, these are vastly overpriced at the Shack. You can generally get them in boxes of 100 for 12-15 bucks at an electrical supply house or on-line. Look for "UR" connectors.

The way I make all the waterproof connections on my boat is to use heat shrink tubing filled with silicone before I heat it.  This makes a very waterproof seal and it's relatively cheap.
