I need some help... I have a 2003 saab 9-3 turbo. It died on me and i had to jump it and when i was driving back it died again while i was driving. I dont kno if its the battery or the alternator.. its never done this.

 

hi there easy way to tell is start the car let it idle disconnect the earth lead (black one)from the battery if it cuts out the alt is at fault if not its the battery.

 

Thanks i appreciate the help
