One Mile Equals a Mile and a Half

On our 2003 Alpine 40FDTS, the odometer is reading a mile and a half for each mile driven. We have put about 17,000 miles on the coach since we purchased it and the odometer is showing an additional 26,000 miles. We checked this on our lastrip by comparing the odometer against the interstate mile markers and it is showing exactly 1.5 miles between each mile marker. Does anyone have a similar experience? Or even better, does anyone have any diagrams showing this instrument and all of its connections?

It must be set to Kilometers, 1 mile = 1.6 Kilometers. On my Spartan frame I can select english or metric. Hope yours is programmable too.

that may be the truth, there is a way to change it to miles instead of K. You would need to get the actcia manual, many folks here have it, you also may in the owners manuals you should have. Check that out, if not send me a PM and your e-mail address, and I think I have it in a PDF format.

I was shocked when I got my coach back from the mechanic and saw it had an additional 50,000 miles on it! Of course a few minutes later I realized that if I hold the button down long enough, it switches back to miles, instead of kilometers. That same button also switches over to a trip meter, which when held down long enough, will zero it out.

The original tire size for the 03 was a 295 R75--if you have since switched tires and gone to an 80R profile [5%] or a 11R profile [10%] your speedo will actually read fewer miles [due to larger tires dia],,,,in this case, it sounds like a metric thing--dealer couldnt explain the 4000 "miles" on our 03 when we bought it new but a simple change back to miles vs kilometers on the speedo corrected the "problem."

PS--hold the trip reset down while the milage indicator is showing total miles [not trip miles] and the speedo will change from miles to kilos or back--think a small "dot or m" shows on the digital face of the milage indicator when its in metric.

FWIW - The dealer who repaired our battery fire damage also replaced the ECM due to its cover being "scorched". They claimed that the first ECM replacement only registered Kilometers and not Miles so they had to return it. This may not be your problem but I thought I would mention it just in case.

This may be wrong but try pressing and holding both MODE and TRIP at the same time.. I think that is how it chanbes from M to K, and back.

And yes it has happened to me as well. . Since I do conversions in my head not so much of a problem.. but then I use the metric system a lot.. So do you if you think about it,, but most folks do not think about it.

(You want to know what metric system you use a lot.?

10 pennies make a dime,10 dimes a dollar, 10 spot, C-note, Grand and so on)

My short course in metric.

You are going down the road and see a sign SPEED LIMIT 45.

You glance down at your speedometer which is calibrated in the same units as the sign. It points dead on 60.

You glance in the rear view and there he is Officer Smiley, Smiling (or course) lights on, pointing toward you and then the curb.

What is about to happen? (Speeding ticket or warning)


Home is where I park it!
