Alternator is no longer working properly.
There is a problem with the charging system.
Take your vehicle down to the local AutoZone or parts store and have them check the voltage output of your alternator. If it's to low/high, this will cause your light to stay on.
MAYBE IT COULD BE A BAD SENSOR. IF IT IS RUNNING GOOD I WOULD JUST IGNORE IT.
Check alternator with a voltmeter A fully charged battery should read approx. 12.8 volts without engine running With engine running reading should be approx. 13.8 - 14.2 volts
Headlights run off the battery not the ignition...
Can be any light in the car as in, under hood, trunk, glove box, etc. Can also be a relay that is stuck. Can also be the battery has a dead cell and is running itself down.
the reason its still running is because your battery has transferred some juice into it already give life for a short period of time.
yes, it dies so fast be cause some apps are still running. if you got to your home screen and on the bottom theres apps that you can scroll through. when they are on that theyare still running which drains your battery even when its off. so if you take them off of that and put it on thewall. your problem is solved.
my battery is still on after changing battery and altnator
ive put in brake fuild oil toped that up checked the battery level all ok still the battery light and hand brake light are still on...
The battery has a temperature sensor. If it was left unplugged, the battery light will still be on
If the light is still on then the problem was not the battery but was instead the alternator which is more than likely defective.
