I'm sorry you are having problems with your vehicle. I will try to help.I'm a full time mechanic and have been a mechanic for over 20 yrs and I work part-time here on JustAnswer to help you and others repair their own vehicles, and I get credited by your ratings.. So before leaving the site make sure and leave me a rating. You can still reply to me as many times as neeed, even after the rating.. I will need for you to be my hands and eyes since I'm not there.So if it's over charging the voltage regulator in the alternator has gone bad. Even tho it's fairly new it needs to be replaced. And if the battery is going bad it can ruin the regulator so have it checked as well.Let me know if you have any questions.Thanks
