Contour Enthusiasts Group Archives Forums General Troubleshooting Odometer stopped working!

Well, instead of swapping odometer motors, I went ahead and swapped the entire speedometer circuit board from my old cluster (w/o tach) to my new cluster (w/ tach). Now at least it shows the correct mileage. Upon careful examination of the two speedometers side by side, I found that the MPH match up exactly and the circuit boards were identical. The only difference being that the numbers on the larger speedo face are on the outside of the lines and on the smaller face they are on the inside. The only problem I faced was trying to get the needle back on so that it read properly. At first it jumped from 0 to 20 without even moving the car. Not good! So I played around with it and got it to move more consistently (and slower) and what I think is the correct mileage. Does anyone know a sure way to get an exact reading on your MPH? Do the scan tools have that option? Or should I just drive beside someone going say 65 MPH and see if mine matches up? What I really need to do is wait for my city to post those speed signs that tell you how fast you're going, then I'll know for sure. Anyway, thanks for your input and I hope I've helped give some advice to someone who's looking to swap clusters.
