Battery light is on. Checked alternator, battery and wires. They are working properly. Not sure what to check next
Check the Belt and tensioner assembly. The battery light comes on when the battery is not being charged. This can be from the alternator not working. Bad connections to the battery or alternator. A bad cell in the battery. If you are seeing that the alternator is charging, my guess would be the battery is faulty or you have a blown fuse.
