Digital Cluster Speedometer

[leefybeaver]

Hey guys, I recently installed a new (used) digital cluster in my 84 Regal to hopefully repair the issue I was having with the previous one which was not having any speed reading or any digital trip odometer reading. While I always have a speed of "0" displayed and a constant number for the trip odometer (the displays work fine) I get no actual speed displayed. The mechanical odometer tics over as it should, so I know the cable is working fine. Is there something I have overlooked with the digital system? I can't even begin to guess where to start with this.

Any help or input is appreciated.

Yes. There is a VSS that is run off the cable that feeds the cluster.

Can you elaborate more on this vehicle speed sensor? Is it in the cluster itself? Can I replace the part that would be broken?

Thanks
