what causes the battery light to on a 2005 ford expedition to come on?
because the battery needs charged or need a whole new battery
Check battery connections, check alternator out put. Exc.
Possible bad alternator.
iT CAN BE EITHER FUEL OR FIRE. taKE IT TO A GARAGE.
The check engine light on a 1999 Cadillac DeVille can be reset by disconnecting the battery for 30 seconds. The light will immediately come back on if the problem still exists.
Does your underhood light come on ? Or if you have the key in the ignition and your drivers door open , do you hear the warning chime ? If not , it sounds like a poor battery cable connection or a dead battery .
Why would battery light come on then go off
THE EASIEST WAY TO DO IT YOURSELF IS TO UNHOOK THE BATTERY. iF YOU DO HAVE A PROBLEM THOUGH, THE LIGHT WILL COME BACK ON.
It's probably your Alternator that is going bad. That is if the battery and brake lights came on at the same time.
Wheel speed sensors, or your ABS Sensor on rear axle housing if so equipped
If it is undercharging the battery yes, but if it is overcharging the battery no in most instances. If it fails completely the light will come on.
