So I bought the Honda NMEA 2000 fuel level sensor that goes from my sending unit to the NMEA 2000 system. I dropped my boat back off to the Honda dealer and he installed both the Honda NMEA 2000 spedo and Tach along with the fuel level connection and also tied it all in to my Humminbird 5 port box. My question is I can't get the fuel level to show on either of the Honda gauges??? I know he tied in the fuel sensor the right way because the level shows fine on my Humminbird. Also I did go in to setting and set engine to "0" and fuel tank to "1". What could I be doing wrong?
