I have a 2010 Grew Grande S 178 B/R with an Evinrude E-Tec 90 outboard on it. I was working on diagnosing an issue with my fuel gauge always reading max full, when I lost all gauge function and radio. My ignition will still start the motor fine, but I don’t get the startup beeper when the key is clicked over before ignition. I do not see any blown fuses under the dash at all and cannot find any fusible links so far. Can anyone help me diagnose the possible issue?
