battery light problem
I have a 2001 Ford Focus. Recently I had problems with it failing to start. The mechanic explained that some of the battery cables had rubbed, and the coil pack was bad. So, he fixed all of that. The only problem is that the battery light comes on shortly after the car is started. I took it back to the mechanic and he checked it all over. He said he tested the alternator and battery and they were both fine. Also, he said he checked all the cables, and that there were no problems there.
Any ideas as to what is causing this light to stay on?
