1986 Buick Regal, the alternator light doesnt completely go off. It gets slightly dim but stays on. I got it checked and was told that it was OK. It was checked while still on the car. Does that make a difference how it was tested. And could it still be bad

It has a bad diode. It may be good now but will fail very shortly
