Reasonable assumption the alternater is bad, but no gaurentee. Hi. The common misconception is that the battery is primary power source of the vehicle and it is in many ways. However, it's main function is for cranking power to the starter. All batteries have a life span from charged to dead (like any battery). The charge in the battery has to be replenished, and that's where the alternator comes in. I suspect the diode in the alternator is bad and the alternator will have to be replaced. A word of caution: if you drive the vehicle for an extended period of time without the battery being charged, a 12-volt battery will be reduced to 9-volts, and at that point systems in the vehicle will shut down. If the battery light is on, the charging system has to be checked to be sure that it is functioning. There are other possibilities that would cause the battery light to come on, however in this case I strongly suspect the alternator.
your fan belt could be slipping
There could be a sensor wire that is bad or going bad
The battery light is to show when the alternater is not charging. A new battery wouldn't make any difference.
check your battery cables. could be old or just loose.
There is something wrong with the charging system. Check the alternator and the battery to see if both are still good. Good Luck!
If you charge the battery and it is not working then there is something wrong with the battery. Batteries are not usually repairable.
you have a short where negative is touching the metal of the car or it is grounded inproperly
on my old 1.2 clio the battery light came on as there was fault with the alternator and it needed replacing. As far as i know the battery light comes on when the battery is not charging or there is a fault with the battery.
either alternator or wrong size battery
Try the battery. Sometimes it seems fine but it is really not.
to take off the engine light take out the positive wire on the battery then hold down the brakes for 30 sec. if the lights still on then sumthing is wrong with the motor
Something is wrong with the Anti-lock Brake System , it could be a fuse , a sensor , or some other problem . As long as the red BRAKE light is not on in your gauge cluster you still have " normal " brakes

Is door ajar light on also?
your altnaitor is out
What you do is get a new charger.that's what is what was wrong with mine
It could be a fuse , a sensor , or some other problem with the anti-lock braking system ( as long as the " brake " light in your dash is not on , you still have " normal " braking ) it means air brake system and it has something to do with your brakes. unhook the battery cable and let it reset and that will tell you for sure if you have something wrong let it reset for 15 minutes

The battery light references more than just the battery. It represents the entire charging system of your car. They may be something wrong with the alternator or any of the wiring associated to the charging system.
The battery light isn't a light like the check engine light...well, it kinda is. It doesn't represent a code though. It's saying that there is something wrong with the charging system, like an alternator or battery going bad. Good Luck!!
Something is wrong with the charging system. Defective alternator would be my guess.
You do not reset a battery light. The light is on because there is something wrong with the charging system on the vehicle. In most cases the alternator has failed and needs replacing. Once you fix the problem that caused the light to come on the light will go out.
it's either your wiring or the wrong alternator or a bad battery !!
you dont.... if the light is still on then that means there is still something wrong
