My Hunter 450 has Raymarine ST60 wind, speed, and depth instruments all mounted side by side above the companionway. On my last visit to the boat I noticed that the wind instrument was no longer working. The back light was working and I took out the unit and could not find any loose wires, also the mast mounted sensor seemed to be functioning normally. The time before at the boat just 4 days earlier it was working fine. I am hoping not to have to go up the mast.:cry:
