My tach started to bounce when the stator was failing. The technician told me this was a common indicator.

Voltage regulator would be my guess. When the diodes short out, the tach goes crazy.

Check the easy stuff first .
Look for a bad ground then go to bad wiring to the tach.
If you find either then its time to check all the old wiring for
trouble spots.
