Crazy Speedo. . . fix found

[Michael Murphy <mmurphy@nais.com>]

After months of tracing contacts on PCB,  looking for the
problem with my 89 100 speedo  (works when cold,
intermittent failure as car warms up, then  either dies or works),
I threw up hands and gave it to the mechanic today.  1.5hrs later
problem solved.  A solder point behind  one of the speedo's 4 prongs
(that plug into PCB), had a hair-line gap causing intermittent
contact/failure.

So when the speedo goes nuts, don't forget to check solder
points on the plug-in prong contacts.
