I have a 2003 Four Winns Horizon 210 with a 5.0 Volvo Penta Gxi. I recently bought the boat and the tachometer and fuel gauge do not work. All connections on the gauges look good. All the other gauges on the dash work. Anyone have or had a similar problem? Any suggestions on testing the gauges to see if it's the gauges or somewhere at the other end?
