I have a 1990 vette. The Tach reads about 3k hi. (shows idle at 3700)
According to the shop manual there is nothing to the tach exxcept for
a connection to the distrubutor and the electronic module in the
distributor. I rebuilt the distributor this wekend. Rplaced everything
with new. The tach still reads the same. Does anyone know of a place
that I can send the cluster to that will can rebuild/repair the tach?
I thank you for any info you can provide. Enjoy your vettes and keep
the shiny side up!
