My vehicle stopped charging. I replaced with 4 different alternators and they were 3 used and one rebuilt that all passed an alternator test at my local parts store off of the car. Even though I was putting crap alternators on due to temporary financial limitations, I'm finding it hard to believe that they were all bad, even a rebuilt one. I have a multimeter and understand the fundamentals of electricity but don't have any flow charts, am not familiar with the other system components or their specifications and want to know how I can verify the rest of the charging system circuit for any other possible problems? Can I verify just the alternator function itself on the car even though they all passed off of the car? The rectangle connector has 4.85 volts and good ground to it. The big cable terminal on the alternator is also reading about 5 volts with the engine running. It read 10 volts with one of the alternators. My battery is fully charged and passes a load test and is a day old. Where do I go from here to not just be guess replacing parts but know for sure?
have the same problem?
