My battery is not charging and my generator light is on in the car. This is the third time I have had this problem in the last year. I have replaced the alternator and voltage regulator twice, and it seems to be solved each time. I just replaced them both a little over a month ago, and the battery started cherging. Then a day later the gen light came back on, and it wasnt charging. The next day when I put the car into park, the light went out and the car was fine. The light has now been on for about a week and it is not charging. Does anyone know what would be causing this problem? Could it be wiring? How would I check this? Could an alternator with an internal regulator solve the problem?
