Hi, returned to the boat and the diagnostics on my NSS 12 say my nema bus is ‘off’. So no instruments showing on any of my displays. Does anyone know why the bus would be off, and how to get it on again?

Check that there is no issue with the automatic fuse for the naw instruments.

On our 445 the bus was "off" when wind instrument failed on top of the mast. It "jammed" the bus so nothing was coming through. We unplugged everything from the bus just below the electric panel and started plugging it one by one to find what was causing the problem.

Thanks Konstantin. I think I will try that, my radio wasnt working so i unplugged the bus and now it works, so i think there is something blocking the bus as you suggest

 Had the same issue, two faulty wind instruments ( replaced under warranty luckily) shut down the system.

Hi both, yes its the wind instrument, disconnected it and everything else is back to normal.

Hopefully the new one will last a bit longer than this one!
