This PC deals with the alternator also. Along these lines, all it would take is a PC blunder and the outcome would be a failing alternator, keeping it from charging. 

#2 – Broken Belt or Pulley 

The belt and pulley produce the mechanical force which gets changed over into electrical energy by the alternator. Your serpentine belt can undoubtedly break on the off chance that it gets loosened up something over the top, making it snap separated. 

The pulley can likewise get harmed inevitably. Regardless, the alternator can at this point don't create a charge for the battery.
