Hi,
Navico technitian came onboard today, fourtunatly the problem arises when he was onboard.
My
installation is so that from the
autopilot switch goes to a relay that activates the NAC.
Guilty...A €7 relay. When the failure arises, the voltage at the Nac was 2,8v, while on the
nmea network remain 12,3. Just moving the relay, the nac becames alive again...
So conclusión, either the relay connectors were damaged or the relay itself.
The technitian has not any relay with him, simply press the connectors, and ...looks like the problem is
solved.
I will replace relay and terminals in the coming days.
Best regards.
