BMW 318I ALTERNATOR PROBLEM

1997 BMW 318i • 203,000 miles

My battery light came on but it seems to dim some when I push on gas also took battery terminal off while car was running and the car shut off.

It should and never, never do that again. It sends voltage spikes all over the place. It is not a test for anything

your alternator has a bad diode. The alternator needs to be replaced
