Stus-List B&G Instrument Malfunction (Wind Direction)

Graham (and all who replied),
I removed the wind instruments last weekend. All of the test procedures I
have seen need to have the instruments installed and powered up. Now I
just need to get my crew to hoist me back up there! I wish I had one of
those cool electric wrenches like Greg Cutter uses to raise his keel. I
will fashion a temporary wind vane, unless I can buy one at a reasonable
price, then reinstall and continue testing.

You could talk to these guys: http://www.myleselectronics.com/ - I would
think they can tell you if it can be tested easily.
My ancient B&B wind instrument has a home made metal vane on it, and still
works - we tested it today for the first sail of the season, gusts > 25kts.
Ironically, the newest instrument on the boat, a Ray ST60 knot meter, never
frickin' works - every season once the boat is in the water I have to pull
the transducer and give it a spin - despite that the thing spun freely out
of the water. Riddle me that!!! :-)
