Could use some help. I have a set TPI-Tech gauges, all are working except for the speedometer. I have done the steps 4 & 5 several times, each time after talking with a tech. After I drive the mile and stop and push the button, the readout says calculating and just stays there. It should, according to the tech, say calculating and then within a few seconds, say done.

The Tech says that there may be an issue with the pulsator generator. Can anyone tell me how do I tell if sonething is wrong with it and how do I fix it.

Better and easier would be for someone to tell me that I am doing something wrong in the speedometer calibration process.

Thanks
