Would a bad VR do this? February 07, 2005, 04:55:14 PM Latly my battery has been dying rather easily. My friend thinks the alt. is going but the car will run just fine. Yesterday the bird wouldnt start, it cranked, but the battery didnt have enough juice to start it. So I jumped it and it ran fine, made it all the way to school. After school it wouldnt even crank, so I jumped it again. I was able to make it home just fine. IIRC a bad alt wouldnt be able keep a car running that long with a battery thats deader than a door nail. Now doesnt the voltage regulator just tell the alt when to charge the battery? Or am I way off? Hopefully its just the VR and not the alt, because I aint got the money for a new one, and I aint going to Autozone for one that will die in a week.
