  1. I checked again today in much stronger wind.  At the server the current between pin 16 (screen) and pin 14 (yellow) was .1 volts.  The voltage between pin 16 and 15 (white) varied from 2.0 to 3.5 volts and varied with the swing of the boat on the mooring.  Coming from the mast, I got the same pattern with screen and yellow reading a constant .94 volts and between white and screen it varied from 2.3 (more North West) and 3.5 (North). 

    I am assuming that the transducer is not providing wind speed information but I am not quite sure why I am seeing the voltage that I am.  If the windspeed data is constant or missing I am assuming that the display turns off.  Does this sound right?  thanks

    Do you have a server and a Multi Control instrument? If yes, is the wind transducer connecred to the server or to the wind instrument? Is wind data lost also from Multi Control instrument and NMEA 0183 output? Do the LEDs blink as they should at the wind transducer port of the server?

    Thanks for the reply- it took me a couple of days to get to the boat.  I have a server and Multi Control instrument.  The wind instrument is connected to the server.  Unfortunately the wind was not very strong.  There is a kind of bus near the mast where the line was cut and joined on each side.  The manual says that the voltages should not be 0 or 5 and be between 1 and 5 volts.  On the white wire I get voltages between 1 and 1.5 and on the yellow wire I get a very steady 0.94 volts. 

  3. I have an old nexus instruments system v. 1.0  from the late 90s.  The wind speed/direction display stopped working this past winter.  I have checked the voltages as outlined in the manual at the display and they appear to be within acceptable ranges.  When I power up the instruments (there are multiple transducers for depth, speed, etc. and a multi control), the wind direct and speed appear.  The speed starts dropping very quickly and dispappears after maybe 10 seconds.  The wind direction appears to be correct but disappears after about 40 seconds.  Does anyone have any ideas about where to start looking?  thanks!
