Well, for starters, there ain't no way this engine is turning 6 grand at 65 MPH. 3 grand or there abouts would be more like it, but it danged sure ain't 6. For another thing, I can't get this thing to idle below an indicated 1K RPM, and it seems happy at about 1.6K, which is almost exactly twice the recommended idle RPM. There for, this tach is indicating twice the actual engine RPM.
What really surprises me is after all of the searching I've done, this seems to be a fairly common problem but I have yet to find a definitive answer. One guy thought it was the tach, another said something about a tach driver, somebody else said it was a bad resistor, and some Einstein said it was a coolant level issue (Yeah right, and I've got this bridge for sale....).
So, is the tach toast, or what?
