My 25 year old B&G AWI just begun to act weird and I am trying to figure out what's up.
On my last sail of about 4 hours, after 45 minutes the wind
speed showed 0 and this was clearly impossible because the wind
was not dead astern and at the speed I was motoring.
As I arrived it began to work again but showed wind speeds over 20 which seemed much too high, although at that location and at that height above the water
it could be perhaps windier than at deck
level. However I don't trust it to be correct.
The wind direction seems to be working, but with no speed report the dial simply will swing all over the place.
So if there is some wind, and it reports none and no wind angle I assume that the wind angle will not work without a positive value for wind speed. When the mast
swings about and there's no wind the wind angle dial also twirls around the dial... probably mimicking to some extent the windvane
at the mast
top. Can watch both at the same time however.
Does this sound like a faulty connection or a faulty bit of electronics
up inside the AWI on the masthead? Could it be a faulty control head
which is not processing the data and the AWI is sending it properly?
What is the best means to test this?
