Gaffrig GPS speedometer-buzzing sound
I bought a boat with a gaffrig gps speedometer that didn’t work properly. I checked all connections and wiring and it seems ok. The instrument makes a buzzing sound a few seconds and the red lamp goes of within seconds. But I can’t se the instrument make a selftest? Broken gps unit? Broken gauge or🤷♂️.
