I read and followed the FAQ for the masthead wind sensor. It appears that the sensor is out of spec. The power supply, at the junction box near the mast, reads 7.94V. Both position sensors are in the 1.6V range. The speed voltage is about the same but doesn't vary in gusty wind.
The failure is intermittent. I used a spare ST60 indicator and the problem shows up with it, too. The ST60's show the wind at 0° and - - - for the wind speed. Cycling power may clear the problem temporarily.
Can I ohm the sensors to find out whether the masthead connection is dirty, or the sensors are history?
