Speedometer & odometer not moving

Speedometer & odometer not moving (PROBLEM SOLVED)
Hi gang, I have a 1994 CBR 900rr.
As the title states, the speedo and odometer aren't moving.
I am mechanically inclined so I have done some preliminary measures as follows.
1) The gauge cluster seems to work fine because when I spin the lower end of the cable with my fingers with the upper end attached to the gauge cluster, the speedo and odometer move.
2) When I connect the lower end of the cable and turn the tire/wheel, I can see the upper end of the cable spin.
3) Cable is not broken in the middle (one end spins the other even under resistance).
So...the tire/wheel does spin the cable. And the cable does spin the speedo and odometer.
Yet when the cable is connected at both ends, the speedo & odometer won't turn.
My suspicions (and I could be wrong): the cable somehow is worn or something is worn so that both ends of the speedo cable are never engaged at the same time.
If I am right....how do I know what part is broken or worn? Which do I replace?
Any ideas?

I am not sure if your guage cluster is very different from a 99 model, but I had a similar experience: speedo, tach and the screen displaying my milage stopped working. The turn signal lamps and oil warning light, etc were all fine. I took the bike in to my mechanic and we found that two resisters on the circuit board on the back of the speedo/tach had blown. He replaced my resisters and everything worked 100% again. Good luck, hope you find the answer.

Thanks guys.
I've got an old school bike; it has a mechanical speedometer that is driven by a spinning cable.
My strong suspicions indicate that there is some wear between the wheel end and the speedo.
The only thing is, where is the wear?
I am going to take another look at the cable ends and both ends that they connect to.
I'll probably need a flashlight...

I found the problem.
It is at the wheel side.
The speedo sending unit AKA speedo drive has a slot that fits in the speedo cable, well that slot broke off and went in the speedo cable.
So I made a thread in the want to buy section for a speedo drive sending unit.
Thanks for your help and support. Will post pics of the break later .
