Alternator/Voltage Regulator I am having a problem with alternators. It seems that I have to change it every year at this time. I just had the alternator tested and it is testing as good; however, when the truck idles, the headlights and inside lights flicker. Could this be the voltage regulator? And is this separate from the alternator? I did look it up and it looks like the voltage regulator is on the alternator as a separate piece. Please confirm and give me other trouble shooting ideas, PLEASE! |
