Electronic tach

[ArthurK101@aol.com]

Folks, I have a 6 cylinder tachometer out of a TRiumph Saloon.  It has 
stopped working.  The needle now goes all the way over to the high end and 
sits there when I turn on the ignition.  I think I grounded it when I was 
working in the dash on the speedo.  I have put the V8 tach back in the Stag 
but want to get the V6 tach rebuilt/repaired (there is a Ford V6 engine in 
the car).

Any ideas for me to repair it or a place which will do it for me?  Thanks.
