More than likely you need a new printed circuit.

Re: problem with tach on a '79 (killain)
Drop the column down enough to get the tach/speedo cluster out. Check the back circuit board for open or cut wires. I had to jumper a couple leads together to get the bulbs to work on mine. Easy work, just be careful not o bend anything beyond it's limit when removing or installing the cluster. There's also the tach filter under the hood near the distributor, not sure how to check that tho.
