temp. guage

[Ingo Rautenberg]

Unfortunately, this is not an uncommon thing to happen to these cars.  I
have a similar problem and have not been able to trace it properly.  As
Bernie suggests, though, Vincenzo, ground the Brown/yellow wire to the body/
engine and with the ignition on  the gauge should be pegged full hot.  You
may have a problem with the connector wire that goes into the instrument
cluster.  I replaced a perfectly good temp gauge until I figured out that
with the Brown/yellow wire grounded  and the instrument cluster loosened ,
that by pulling it out slightly, the gauge would come back to life. Mine
works fine 80% of the time...more pressing things to attend to...
