I checked the voltage with the in-dash test mode, which I believe is pretty reliable (is it ? ) . The lcd wouldnt display 12 v till I hit 3000 rpm and the battery is less than 6 months old so I figured the problem had to be the alt. I havent run the car since the problem appeared. Its gonna get repaired tomorrow morning probably so i'll know for sure. But thanks for the answers, i'll let you know if the alternator was guilty of the bad running of the car

thanks !
