Why is the alternator not charging?
– Broken Belt or Pulley. The belt and pulley produce the mechanical power which gets converted into electrical energy by the alternator. Your belt can easily break if it gets stretched out too much, causing it to snap apart. The pulley can also get damaged after a while. In either case, the alternator will no longer be able…
How do I know if my battery or alternator is bad?
Signs of a bad alternator. If the above steps reveal that the battery is working, it’s time to take a closer look at the alternator.
