While your comments are helpful, I have been attempting to do just that.........Diagnose the problem prior to changing parts. If you have a way to test the motor, I am all ears.
No one else has suggested that there was a way to do this or even indicated what type of voltages one could expect. I did ask exactly that.
I assume that none have given this advice because the typical shop experience would be to diagnose the cluster and replace it. Possibly to replace the entire assembly for the speedo but as previously mentioned, I have had the motor out of the cluster and inspected it.

You are 100% right; most times we here in the shop diagnose that the cluster is at fault and either replace it or send it out for repair. I have looked myself trying to find repair specs and procedures for clusters; but they are not easily found.
Most of the automotive electronic repair facilities that are local to me; admit that they had to learn the hard way and dove into these things with trial and error. Once they have the info they need to do these repairs, they become very tight lipped with it.

Dan,
Thanks for your insight. It hadn't occurred to me that the signal was pulses to the speedo or odometer, I assumed it was a voltage range like 1-5dc.
Also, encouraging to hear that you were able to get a stepper motor to work across such broad platforms. Gives me hope that one of the same manufacturer for a given year will almost certainly work. Kudos to you for your triumph with that project!

Talking about pulse per mile; does your truck have cruise control; if so does it still work?
If it does that would tell us that the Speed sensor is sending a signal, the ECM (computer) is deciphering it and sending out the signal other units need.; speedo & cruise.

wow that's an excellent observation! I had not thought to ask, my son drives the truck.
He confirmed that cruise control works perfectly!
Armed with the knowledge that the stepper motor is almost assuredly the culprit, I think I may take it apart a little further in an attempt to repair it.
Junkyard part if all else fails.
THanks for your insightful comments Dan!!!! I will repost when the speedo is fixed.
