instrument cluster weirdness

Your 'new' flexi-circuit has a fault in it more than likely.

imo...

Subject: instrument cluster weirdness



Last night I replaced the instrument cluster, which has developed a
broken trace on the flex circuit, with another used one, supposedly from
the same year Scirocco (84) and which looks visually identical, MFA and
all.  The replacement unit works fine -- except -- ONLY when the
headlights are off. As soon as the lights are switched on (even the
parking lights), the tach, fuel gauge, temp gauge and instrument lights
all die.

I researched this in the .org archives and a couple similar problems are
in there, and the advice was to check for a ground problem, and there
was no response as to whether that solved the problem.  Anyhow I can't
see how a ground problem could suddenly develop when all I did was
exchange the clusters.  I was very careful to disconnect the battery
first, take my time wrestling the cluster out, etc.

Anybody ever had something like this happen?  Are there differences in
the pin-outs of the cluster connectors from year to year in that era,
1983-85, that could account for this weirdness?  Any help most
appreciated!
