This will be of limited interest to people with other instrument brands, unless of course you are shack happy and have been away from your boat too long {grin}.

A couple weeks ago I posted that I was having trouble with my ST60 wind instrument. I do have a replacement masthead connector and inmast cable assembly paid for and arriving today, thus assuring that I could find another solution in the meantime!

Using a document showing the pinout of the masthead connector (see web link), I found that I had just one bad connection (out of five total), the starboard direction sensing lead.

Yesterday, I hammered flat a length of monel seizing wire, went aloft, and inserted it into the problem female connector, and pushed home and secured the masthead wind unit. This was successful and I think stands a good chance of lasting as long as I leave it alone.
-------------------------------------

I did some other tests along the way, doing voltage measurements at the display head. I found that the anemometer was working fine (showed best with the AC meter setting). The port wind direction sensor was good too. As mentioned before, the display was showing only the "line of death" and 0.0 for wind speed. On a hunch, I bridged the good (port) sensor lead to the starboard direction input (after disconnecting the bad starboard input lead). Now I had both inputs getting the same value. This produced a meaningless wind direction but did yield a good relative wind anemometer reading, useful to have.

I can see why Raymarine defeats the entire display if the wind direction is bad. Think of the chaos if the autopilot got switched over to windvane steering mode!
