my voltage regulator on my alternator crapped out a couple months back the alternator was only a year old. measure the voltage with it running should be around 14 then turn on the lights and the ac. see if it drops to 12 volts or so, if it does your voltage regulator is going. I pulled my alternator out was going to spend the several hundred for another one. but no one had one in stock so on a whim i took it to a alternator repair shop. He tested it and said nothing was wrong with it and wouldnt charge me anything. I was only having the problem when the engine was heated up good. when i told him that he said the voltage regulator might be going and failing when hot which he couldnt duplicate. So i bought a genuine porsche voltage regulator and the problem went away. The old one looked a little burned when i took it apart.
