[C320-list] Wind Instrument Malfunction

[Chris Burti]

We had ST-60 instruments (still have ST-60 sensors, but upgraded to i70
instrument) I ran the tests that Raymarine tech advised, no joy. Sent the
head in to be tested, passed, sent the vane in, it passed... gave up and
bought a new vane on eBay..works fine now.
