      I think this is a physical problem with the weather vane design. I’ve watched the vane flip back and forth a lot. This problem occurs night or day. Today there has been no direct sunlight. It’s been raining most of the day. I don’t think it’s the sunlight interfering with the leds.

       

      Here is a good example:

      http://www.wunderground.com/weatherstation/WXDailyHistory.asp?ID=KTNCOOKE13&graphspan=day&month=5&day=1&year=2009

       

      It rained and was cloudy most of the day. Plus you can see that it’s erratic during the night hours.

       

      Here’s the same day on another local station:

      http://www.wunderground.com/weatherstation/WXDailyHistory.asp?ID=KTNCOOKE13&graphspan=day&month=5&day=1&year=2009

       

      and another:

      http://www.wunderground.com/weatherstation/WXDailyHistory.asp?ID=KTNCOOKE10&graphspan=day&month=5&day=1&year=2009

       

      As you can see, mine (the first) is much more erratic than the others.

      My personal opinion is that the vane is too well balanced, so what I did was to put more weight on the tail using foil tape. Reaction time has been slowed

        My personal opinion is that the vane is too well balanced, so what I did
        was to put more weight on the tail using foil tape. Reaction time has
        been slowed some, but the readings are now more reliable (at least for me).

          http://www.turnto23.com/news/19357602/detail.html

          The Tehachapi Pass is a major highway and railroad artery between the California Central Valley and the rest of the country.  The pass is home to hundreds of electricity generating wind turbines and now one is running amok and shut down the railroad and highway, maybe for days.

          Just a little perspective, hope you get your problem solved soon!  :-)
