fastbird232 Posted April 2, 2005 Report Posted April 2, 2005 I'm looking at buying another Grand Prix, this one's an '89 SE 2.8 (2-door) with all the bells and whistles. The guy says it's been frying alternators left and right. He says it's probably the voltage regulator. Now, where is that on our cars, and will having a donor Lumina Euro 3.1 (roughly the same year) help me any? Quote
93CutlassSupreme Posted April 2, 2005 Report Posted April 2, 2005 the voltage regulator is integral with the alternator Quote
fastbird232 Posted April 2, 2005 Author Report Posted April 2, 2005 Why does it keep frying, then? Quote
93CutlassSupreme Posted April 2, 2005 Report Posted April 2, 2005 a weak battery? a short somewhere? i don't know Quote
94CutlassSLCoupe Posted April 2, 2005 Report Posted April 2, 2005 Blown fuses would cut a shorting out circut off from working...so that would keep the alternator from extra load. I would bet that the alternator lead wire or another important positive lead is probably chaffed and arching to the body, putting extra strain on it and then shortening alternator life. Quote
