What is wrong with the one you have? Are you sure the volt light in the dash isn't holding it back?

the one that i had was making allot of noise, like the bearing was going out, plus it would vary on charging from 13.2-13.8 volts on scan master. I changed the dash bulb when i had the dash rebuilt ( digital) As far as i know the charge light is good .
i installed a new 120amp alt and its showing 14.2-14.6 volts i like that much better
