Faults and Fixes
Why does my chartplotter or VHF fail to start or freeze?
Most electronics faults are in the supply and the data network rather than the unit: voltage drop, an oxidised connector or a conflict on the NMEA bus. Replacing the device can simply move the problem.
Why it works this way
In a helm survey every unit is powered up and confirmed to be receiving data, which is what separates "present" from "working".
