Thanks for the info. I believe the wind data is sent directly to the displays, hull transmitter not involved. Wind has worked from the beginning, even before I re-installed & re-powered the hull transmitter.
I thought there was some type of diagnostic mode, just couldn't remember how to access it. My manuals
are MIA and I'm having trouble finding downloadable manuals
for the older components. There are some FAQs on the Raymarine
site regarding entry into the HEALTH
diagnostic mode, but I'm not sure if that applies only to the newer 100-2 displays. I'll give it a try and see if I can get any info.
Another FAQ talked about waiting at least 6 hrs. after giving the Hull Transmitter power before testing (guessing for battery recharge -- assuming it's still good
). I was just testing with direct power, so I've left the power to the instruments on now and I'll re-test later today.
Hopefully I won't have to replace the battery but I'm guessing that will be the eventual outcome.
