ST 60 Wind Display

[Geoffreykwright]

Hi.  I have an ST 60 Wind on my helm.  Its worked perfectly for more than 10 years.  All of a sudden (yesterday) the wind direction (on the display) seems to be about 90 degrees of both the wind-vane on the top of the mast and the smaller wind vane on top of the "cups".  The mast head vanes seem to indicate the correct direction - the display on the ST 60 seems to be off.  The wind-speed the ST 60 is reporting seems to be correct - just the direction is off (by about 90 degrees).

Has anyone run across this before?  Thanks in advance.

Hi Geoffrey,
I have a similar problem with my ST50 wind instrument except in my case, the display wanders away from the apparent wind direction and can end up displaying wind 180 deg from actual.  I suspect the connections at the base of the mast.  I hope to inspect further this weekend.  I found this on the Raymarine site that may be helpful.

Let me know if you're able to correct your problem and I'll follow up with anything useful I can find.
