The reason i ask is i just got a 220A alt however the person putting it in used the factory pulley instead of the one on the alt because he did not see to use a smaller belt. But i get less voltage now at idle than i did with my stock alt. When i get it up to 2-3 rpms the voltage kicks in but just cruising it does not do much better than my stock, around 1500 rpms. Will the pulley make that much of a difference or did i get a bad alt?
