careful of "not good answers". use a simple voltmeter to test if you're battery is being charged when the engine is running. if it is, check the gray wire from the rectifier to the dash. if it has continuity, it's the tach. oh, most important, make sure when the key is on you have 12v. to the tach.

First check your connections on either end. Be sure they are tight. If that doesn't help, buy a new tach.
