Raymarine forum

so I have a full ST60 package, wind, speed, depth. Wind cups were damaged. Cups replaced, instrument worked fine for a few days and went wacky. ST60 wind inst powers up but no data displayed (no needle movement). How can I T/S the wires coming down (what voltage should be on red etc) and how can I T/S the display assuming the information is making it through the wires.

Hello Eheim,

There are voltage measurements for the windvane on this FAQ. I suspect you'll see incorrect voltages on either blue or green (the wind angle pair that the system uses to detect that the windvane is there.

Regards,
Tom
