What causes a battery not to charge?
One of the most common reasons the battery light comes on and the car battery stops charging is because of corrosion. Whether the corrosion is on the battery cables or cable terminals, it is still a problem that needs to be addressed. Another common culprit for the battery not charging is a problem with the alternator.
What could be the problem if your charging system is not charging the battery?
This means that you could have a weak alternator, or a poor connection at the battery terminals. You could also have a loose drive belt, which is what supplies power to the alternator itself. If the drive belt is loose or not working properly, the alternator will not charge.
How do you fix an alternator that is not charging the battery?
Check the large power cable to the alternator and the fuse, usually, a large 40-60 amp fuse near the battery. Check the ground cable between the engine and the body. Check the serpentine belt and make sure the alternator is spinning with the engine. Check the small power supply wire and the charging light wire.
