I have a new battery on the car but the battery light is on in the dash. Turns out my car is running on my battery until there is no juice left in it, then it dies.
I thought it was my alternator so I purchased a new one. Got the new alternator installed and the battery light is still on. When I turned on the car with the new alternator, it runs until the battery juice is out then cuts off.
All of the grounds seems fine and everything is connected.
