... following up on your post couple months ago Charlie, my ST60 WIND instrument is not registering any data. I also have the ST60 MULTI and the Wind Chapter doesn't even show up, skips right over that from Speed to Heading; and no Wind information coming to the Plotters. I am just now commissioning my mast, which was stepped the other day. I had damage to the spreaders caused by the yard, so there was some fabrication work being done on the mast last week, it's possible they nicked a wire although all my mast wiring is inside an aluminum conduit, so protected. The anemometer base & cable, Raymarine part A28162, were new last year, w/two different locations of wire ties masthead for strain relief. The Anemometer bird is not new, but it seems fine, everything worked fine last year.

I am getting no readings on the Display, only ---'s, and the needle doesn't move when powered up. When I meter the J-box connections (crimped and/or soldered ring terminals) at the base of the mast with the instruments on, all my readings (red-shield, blue-shield, green-shield, yellow shield) are all under 1v, range between .866v to .23v).

When you were troubleshooting, were you getting good voltage readings (8v red-shield, etc. like the Raymarine link says > http://www.c36ia.com/files/ST50-60%20Wind%20Troubleshooting%20with%20Masthead%20pin-outs.pdf) at your connections at the base of the mast, BEFORE the run up the mast ?

I'm trying to figure out how to troubleshoot and isolate where the problem might be ...

thanks, cheers, John
