If it`s like mine the tach drive just unscrews, you should be able to remove the cable and look to see if it spins with the motor running.
Yes: cable or tach bad
No : tach drive issue

Undo cable at both ends. Remove cable from sheath noting which end is top/bottom. Spray any solvent thru sheath. Clean cable with any solvent then grease it. Put it back together, re-install.

Somewhere in this process you will discover if the cable is good or bad. Do all this even if the cable tests good as in the previous post.

I replaced my original 1980 mechanical tach with an NOS 1981 electrical version from eBay. Looks the same but no cable. Really nice to have that cable gone.

I see the older tach at a good price on ebay quite often. I'd keep it stock.
