Wile out this past weekend, the wind instrument in the cockpit was freaking out, the needle jut jumping and spinning randomly, jerking around. The wind speed was also moving about quite a bit. A guy at the marina mentioned that maybe the electronic wind gauge atop the mast must have come off. I'm looking at the top of the mast from the deck but I'm not sure what it would look like. Couldn't the also be caused by a cable short? How to test and determine this? Any thoughts would be greatly appreciated.

Thx,
Tony

Probably O.K.

Luken,
My guess is that you still have the instruments at the top of the mast. You would get no readings in the cockpit without the transducer up top. My wind instuments often "act up" this time of year because of spider webs on the transducer. The instrument in the cockpit is making calculations involving wind speed, wind direction and boat speed. If the anemometer portion of the transducer is bound up by spider webs, then it comes to the wrong conclusions about wind speed and direction. Try toggeling back and forth between true wind and apparent wind to test this theory. A real strong breeze will "unstick" the spider webs and usually cure the problem.

Just got over to the boat and darn if the windvane isn't gone. The wind speed indicator is still up there spinning, but the direction vane that is supposed to be there isn't. The set screw that holds it there must have gotten loose and finally come out. Now the challenges to find just that part,who hideout. Raymarine sells itself. Will hunt around.

i also at the end of the season had some ST-60 wind issues. No speed. there is somewhere on the Raymarine site info to troubleshoot and I was getting strange readings. Made no sense.

I sent the head unit in and they gave me a new one re-built for a bunch of money.

I put it in and still no speed, just direction. So....I bought another new transducer. I am on the hard and may try hooking the new transducer to the back. I only bought the screw on head, no base. I hope its not wiring thru the mast.

NOTE:
I will be happy to ship you my old transducer for the parts which seem all in one shape. and all of the spinning cups are there. I also have the very nice box the new one came in, which would be easy to pack. Totally up to you. bad part is the yard will not get to changing it for a couple weeks or so. They have a cherry picker to go up.

Ironically I had an extra base unit, with the spool of cable, in my workshop for three years. cleaning up this a year ago I tossed it out as I thought I would never use it and who would buy it. that was stupid but I end up collecting soooo much crap. Will feel more stupid if I end up buying a new base!

Craig, thanks for the offer, I may take you up on it. I had just tracked down a spare this weekend while down at the boat, I'll see how that goes.
