well the alternator i have on now is a lower mileage that i bought from a fellow member on CGP. the original alternator i had was making grinding noise(prolly the bearings) and with the voltage booster even on the old one the voltage was about the same. the voltage booster i have was bought from ZZP(i'll e-mail them to let them kno). i did noticed when i installed the lower milegage alternator the voltage was above 14.9 for a day or so(did a cam swap) and my radio was working w/o issues/interference because i got the low beams only HIDs.
