I have a 78. The speedometer registers speed and mile, but the tachometer sits lifeless. Where do I begin the investigation?

Once you confirm it is plugged in then test to see if it is the filter. By pass the filter by plugging your tach wire directly into the distributor. If it works then buy a new filter. If it doesn't then it could be the tach board. Willcox also offers videos: https://willcoxcorvette.com/corvette...78-79-usa-made
