My datamarine mast unit isnt registering wind speed. Its that common issue from moisture collecting at the base and sitting on the circuit board... Now I was told that back when Datamarine was in business they had a rebuild kit they sold for this part. Does anyone know somewhere that might have that rebuild kit? maybe sitting at some shop in that corner closet with old out-dated parts? has anyone tried rebuilding it themselves without a kit? Im trying to avoid buying new electronics for another couple years and I enjoy the repairs as a hobby...
