My 180 MF tachometer all of a sudden is not accurate. When it is around 1700 rpm the tach shows 2000 rpms. The needle doesn't stay steady.How do I know if it is the tach or the drive assemble?The tach only has 54 hours on it.

If the needle is jumping a lot I would suspect the cable is binding, maybe try some lighter lube that can run down the cable.

I'd suspect the tach, the gear drive on the alt/gen rear will probably break/quit completely and stop turning the cable instead of jumping around like that. Is the cable well lubed?
