Well, at least I don't think it's the usual problem.  For starters it still
works.

Last time I reset it the button stayed in but the trip odometer kept
rolling.  Now my mechanic was fooling around with it after this came up
because my speedometer was making noise after having the wheels pulled off.
The odometer reset button popped out and I suspect didn't get aligned with
the opening properly, possibly resulting in the speedo cluster breaking at
the two screws where its connected at the top.  Hopefully this is a
coincidence and not some goof my mechanic didn't own up to.  So to sum up:

My trip odometer works but won't reset, and
The cluster won't fasten properly to the housing.

What to do?

Oh, and why is there circuitry running to the speedometer?  I thought it was
solely a mechanical unit.

Last but not least I never reset the odometer while moving, myth or not.

Thanks again
