2005 SRT 6 voltage drops and battery light comes on under acceleration. Belt is not loose or worn. If I pull the positive battery terminal while running the car dies like turning off the key. Thinking the alternator is bad but when I looked at replacing it there seems to be a ton of confusion in the marked as to what actually fits the SRT 6. I have tried to weed through all the threads regarding this issue but have still been left a bit confused. Apparently I need to identify whether the car has a Valero or Bosch? How do in make that distinction? Some sites seem to show a direct replacement but describe a 6 groove pulley instead of 8. Thinking I should buy locally because it may take a few tries to get the right one. Any input would be appreciated
