Replaced mmdc and still nothing.
Today I replaced my mmdc on my 2003 x10 and my gauges still don't work. I bought a new mmdc from medallion and my gauges still don't function at all. The plugs all have power and ground that go to each gauge. I even tried only plugging one gauge in at a time. I checked all fuses and wires I can't figure out what the issue is. The boat starts and runs but I do have a check engine light on. Anyone have any ideas or tips I can try.
