Oregon04Windsor Posted September 9, 2021 Share Posted September 9, 2021 The speedometer on my new-to-me 2004 Windsor is reading incorrectly. At 55MPH or so it's reading about 35MPH. The Aladdin display reads the correct MPH so am I safe to assume it is a gauge issue? Is there a kilometer switch or setting on the speedo head? The only button just seems to by trip reset.

waterskier_1 Posted September 9, 2021 Share Posted September 9, 2021 Many speedometers have DIP switches on the back to set them up. Did you check your wiring diagrams? That is where the switch setting are shown for my 05 Exec. Link to comment Share on other sites More sharing options...
Rick A Posted September 10, 2021 Share Posted September 10, 2021 This speedometer isn’t digital it’s a manual speedo. The dial has a conversion on it so you read the miles/hr on the outside scale and the km/hr on the inner scale. If you have a GPS it might tell you what speed your doing. That way you celebrate the error factor and maybe you could see if the dial face has slipped out of alignment? Link to comment Share on other sites More sharing options...

The Aladdin and my GPS does register the correct MPH, it's just the speedo itself that's incorrect. I'll inspect the back of the unit for dipswitches and hopefully get lucky that it's set to kmh. Would seem odd since coach has only 14k miles and two owners, near as I can tell was always a US coach. Link to comment Share on other sites More sharing options...

The speedo isn't reading kilometers, if it was, it would be reading higher than true, not lower. 1 Link to comment Share on other sites More sharing options...
