Speedometer not working

[John Lagnese]

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 
soldering.

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. ;-)
