FI 5001 no wind speed

We are currently in Colombia and the digital wind speed only reads 00.0. The wind direction is correct and displaying perfectly and the masthead unit is operating normally....the vane is finding direction and the cups are spinning......any thoughts???.
Impossible to change unit without pulling 72’ mast and that cannot be done here...no cranes large enough...
Could this be a connection?
Three units are stand alone.....wind, depth and multi display...no additional connections to other electronics. Worked perfectly, then it didn’t......
 
Could this be a connection?

Yes, that is the first thing I would check for. I would start at where the mast sensor connects to the cable at the little junction box. Looking for good connections with no corrosion. If that looks good; it sounds like the servo might have gone bad.
 
Thanks for your response......we will begin tracing wiring and checking connections tomorrow....will let you know what we find.
 
Thank you for your help.
Disassembled dashboard where instruments are mounted....large aluminum hood over companionway....and wind speed appeared on instrument. Connection behind instrument stressed. Replaced connection and wire tied to better position.....
Best outcome possible in remote location....no pulling mast, no need for FedEx delivery of parts.....
Great to know this forum is available for support. Thanks.
 
Referring to previous post that stress on connections caused no wind reading. Apparently not true. No readings now for speed or direction. F1-501 using F1-5002 and AT10 converter. AT10 blinking green, when power applied F1-501 beeps but will stop when 2-3-or 4 button pushed but icon on screen still blinking. Sign of no data n? AT10 blinking green sign of no data in? Can’t find junction box for anemometer cable so is it possible to test at pins going into instrument? Wire code designations for pins? Ohms?
Thanks from frustrated sailor healing 45 degrees at dock in Santa Marta, Colombia.
 
Unfortunately there is no good test on the wires from the ground. It is a pulsed/clocked signal. You could maybe see the signal with an oscilloscope but Japan hasn't shared the exact signal provided to compare with. The FI501 has a setting to see wind data on your NMEA 2000 bus if you have a NMEA 2000 source. You could always see what the display shows when shifting to a diffrent source. It is almost never related to the display. It is mostly 1) incorrect user setup 2) wind sensor wiring 3) wind sensor itself.
