Re: Tachometer (RPM) Trouble

[Kris Tewkesbury <tewkes@engin.umich.edu>]

Chances are that this problem has to do with your printed circuit ribbon 
behind the dash console that includes the speedo, tacho, etc.  Mine did 
the same thing.  Ended up being a short on that cheap ribbon circuit 
paper stuff.  Look in the Bentley for insight.  TO fix mine, I had to get 
a whole new instrument cluster.  $$$$$$
