I have a 1980 TA, nonturbo 301-tach is stuck all the time at the 4500 rpm mark.

Mechanic says the tach is probably bad and I have asked how can you Troubleshoot this without taking down the dash?

Is there a power supply etc that can be tested before doing anything invasive?

Also maybe important to know that the original carb was replaced by an Edelbrock before I bought it.

Any thoughts would be great.

Thank you,
Paul, Naples, Fl.
