I enjoyed the beautiful Fall weather here in Georgia the last 2 days, covering around 200 miles. Last night, I noticed my tachometer is bouncing in and out. Is this a cable issue? Thought, ideas, experience, etc. appreciated!
 
Very likely. Pull the cable and lube it. Also lub the gear box while you are at it.
 
If the cable binds, you stand an excellent chance of breaking the gearbox; don't ask me how I know.

What you describe can also be internal to the tach. You can make sure the cable is free and not binding pretty easily. Then, if the bouncing continues, it's gotta be in the indicator.
 
or it could be electrical, if by bouncing in and out you mean it works stops works stops. Check the fuse block connections.
 
Think it is a Bugeye with a mechanical one.
