I have the 6G Alt in my car, and at idle the volt meter needle likes to bounce up and down along with my idle but when I am cruising the needle stays at a solid 14V. My idle will only vary a little bit, maybe 50rpm, but my voltage will go from like 14V down to 11V and then bounce from 11V to 8V. Is the voltage regulator shot on the alternator? If so then why does it stay steady when I am cruising? Is my battery not good enough?
Thank you.
Thank you.
