Yeah, my needle was jumpin' too...

I already had a good alternator on it, and the battery was nearly new...the wiring harnesses (both engine and lighting) were replaced. Put new belts on the engine and whoa! Now the volt meter needle just sits there. No fluctuation. No nothing. So, what about your alternator belt? Is it loose? There shouldn't be but a slight amount of deflection when you press down on it between the alternator and the water pump. If it goes down as much as a half-inch, it is too loose. IF the back side of the belt has a smooth, shiny, glazed look, it could be slipping. Belt dressing may help, but be careful with it.
