I know how fast but not how far?

My 1986 560SL has a good working Speedometer but the odometer and the trip odometer is not working. Can anyone give me some advice on how to start trouble shooting?

Reading your M103 duty cycle:

So what your telling me is that the numbers are turning on the shaft.

Great Info. I can't wait to get started.

Thanks you so much
