Issue started as intermittent windspeed/direction from a Garmin
GWS-10 at the top of the mast
. It was not showing up on the network at all when not working.
First, I replaced a suspect looking field connector at the mast
step. Then plugged the instrument in at the bottom of the mast inside the boat
. It worked fine. So I reinstalled the GWS-10 back on top the mast and worked for about a day.
While up the mast I noticed the mast head NMEA service
connector was somewhat corroded so I went ahead and replaced that. I also tried adding an inline resistor at the top of the mast and that didn't help.
Next I removed the instrument again and plugged it directly into the t connector on the back bone and it still doesn't show up on the network. I also swapped the GPS antenna
and the wind
instrument on the backbone. The GPS antenna
shows up when swapped but still no wind
How common would it be for a GWS-10 to go bad?
