My ST 60 wind
instrument displays only '0.0' for wind
speed and the direction arrow is intermittent...seems to work
accurately on a starboard tack but stays centered on port tack. The sender is not blocked and all looks fine at the masthead (I haven't been up to look closely). Removing the display is possible but will require some major reno so I am reluctant to do this until I know if the problem is at the mast head
or at the display. This problem is very recent....what happened?
