Ok, so I have searched and found nothing to do with what I am talking about. I have a 2001 XJ. When I drive the voltage gauge says 14-15v. Occasionally it will peg to 19 and the check gauges light comes on. It will usually stay on until I come to a stop or it will turn off by itself. Or my radio will just shut off while I am driving or when I am putting the windows up. When the windows go up the needle will go down past 14v and the windows go really slow. And the interior and headlights will flicker all of the time. I had the alternator checked on the car at advance auto and he said at idle it was putting out 2.5 amps roughly and 14volts. He said it might be the alternator but I talked to San Hose Generator to order a new one and said that it sounded like the regulator (which is external). I dont get any other symptoms and no check engine light or codes. Please help!! Thanks!
