[DG] [DG11] ST60+ Masthead Wind - Reasons for failure

[[email protected]]

I finally did a biopsy on the failed WindVane to see why it died 2 years after it was repaired by Raymarine, which to me seems a very short period of time. From the picture it is apparent that it died from moisture intrusion. The ORing appeared to be dried out w/several cracks. Why this critical part is not covered in 5 cents of
waterproof coating is beyond me. The unit I replaced this one with has now also stopped working and this is only after 3 months. I don't know yet if it is wiring or a unit failure. Extremely frustrating.
