This could happen for different causes.
1. Your battery is making contact with a surface (like the hood, seat frame or trunk battery holder.) in BMW 325 or Cadillac north-star cases.
2. The positive cables from the alternation or starter are bad and making contact with the engine, manifolds or body (create a short circuit for a couple seconds and cause the light to come on for a short time period).
3. Alternator plug loose.
4. Engine ground cable dirty (in the contact area) or broke.
5. Alternator is about to fail (should charge 14.5 volts.)
6. Alternator belt is not properly adjusted.
7. Or your car is possessed by demons. lol
