I had the annoying bouncing speedo needle. The fix was to resolder as shown
in picture 2. Thanks Phil!!

Peter may be right, however defective
solder-joints in the instrument cluster are also
a common cause for the speedo malfunction
(completely dead or bouncing needle). A quick
"test" (done carefully while driving, of course)
is to give the top of the padded dash a good
smack. Might take a couple of hard hits. If that
succeeds to get your speedo back to normal
behavior ( at least for a brief time) you'll know
you need to pull the cluster and do some
Photos of my repairs here (includes wire jumper
added to fix hi-beam and turn-signal issue):
P.S. My resoldering job (done at the base of the
2-pin connector) solved the speedo bounce problem
for a few years. It recently has reoccurred, so a
more permanent repair is obviously needed. This
would require somehow (?) directly connecting
(i.e., soldering) a ground feed wire to that pin.
Or continue slapping the dashboard until it hurts
your hand too much. ;-)
