Yes. That is the ‘old thread” with pictures BUT no pictures… As stated in that thread, there is nothing on the web showing how to do a newer ST60 with egg cups. I am struggling to see how to even open it up without causing damage!!!
Once again, any guidance greatfully accepted.

The ST60 egg body just unscrews to open:

At last. Thanks very much, that is just the info that I needed (I didn’t know that it unscrewed and I was trying to prise it apart - hence my fear of breaking it which has been vindicated…)
That‘s the first video that I’ve seen with the ST60 cups.
Once again, the Forum has come through with the goodies.

Thank you for this. I had seen that PDF before.
Unfortunately it is for the older wind vane but there is still good info in there for me and will certainly help so, thank you.

A stupid but related question before travelling up the mast but how easy is it to remove the wind cups? Our unit reads direction fine but cups not turning ?

Not stupid, I had the same thought before going up when my cups stopped turning…
The unit is just a pull/push and a turn. It’s quite easy to remove/replace. I wouldn’t mess about with the cups up there. I brought the whole unit down to work on, safely inside. The cups come off easily with just one cross head screw.
BUT either have someone down below to mend it and stay up there or just bring it down and have a rest!!!

I replaced my old 2005 windvane with a new one last May, lost windspeed and subsequently direction became unreliable.
I thought I'd do that, overhaul the old one (bearings and PCB) then sell it to recover part of the cost.
My partner hauled me up the mast armed with tools, plus-gas, WD40 and all manner of stuff then went below to put the kettle on. 30 seconds later the old one was off, the new one on and I was shouting at her to turn the instuments on to check it worked which it did.

When I’m next in cowes maybe I should offer you a repeat performance ?

I'm also trying to repair an old ST50 wind vane on which one of the SS94A1 sensors is toast. Unfortunately the part is unavailable from Mouser (39 weeks lead time some time in 2023) and Digikey. The only other source I found was RS where the price is in the order of 220 euro (!). Any other source that comes to mind?

So having spent an afternoon remaking connections where the cable joins after having my mast re- stepped I’m faced with a wind instrument doing exactly as this picture shows....a bit of rain (well, a lot of rain) and:
So the reason it wasn't working on my friend's boat was that the transducer lets in water.
Sigh. The old transducer has gone off to Paul to be fixed then back up the mast I go... at least it's keeping me fit...
Edit: For anyone passing this way in future with similar woes, if you swap an OLD transducer (square cups) with a NEWer transducer (semi-circle cups), the gray ST60 instrument above will overread the wind. You need to configure it to 0.75 of wind to correct this. Thanks again to Paul for that nugget of information.
The mast was down for about 8 weeks and the weather was pretty foul so could easily be less than perfect connection between the transducer and the socket or a problem with the wiring between the socket and the display unit itself.
before I venture up the mast, is there anything else I can check / do at a sensible height?
Having cleaned up all the connections inside the boat my gut feeling is there is some corrosion between the masthead unit itself and the socket it plugs into but keen to exhaust all other possibilities before tackling that Anyone got any pointers??
and if that is the likely problem- any suggestions for fixes that can be done at the top of the mast in a single trip as multiple trips up and down is not top of my list of fun things to,do. It’s a long way down!
