I have been troubleshooting a nonworking speedometer that occurred after I
had the instrument cluster out.

I have done the following:

1.  When I pulled the flexible shaft out of the upper housing and put it in
the speedometer and twisted the shaft, the speedometer responded.  I presume
this means the speedometer is okay.

2.  When I feed the shaft back down the housing and made sure that it had
dropped into whatever hole is at the bottom, the shaft would not turn.  Does
this mean that I have gotten the shaft in the right position?

3.  When I drove the van, the shaft was not turning.  What does this mean?

What do I do next?  How do you troubleshoot the device the connects the
upper and lower cables?

Have I missed anything obvious?
