Troubleshooting battery warning lights that comes on
When your battery light comes on while driving two reasons will cause this, first is the alternator belt is broken and second the alternator failed. The alternator is being driven by the engine using belts for the purpose of supplying charge on the battery and provides electrical power on all of your car accessories. If the battery light comes on while driving it means that the alternator is not generating electrical power for your car and all the car accessories will draw power to the battery until the battery also losses power. Now why the alternator is not supplying electrical power to the battery and accessories?

Two reasons are causing this, now pop up the hood and look into the alternator. Check if the alternator belt is damage if the belt is intact then the problem is the faulty alternator.
