I just change my battery in my 1998 bmw740i, and the battery light is on. What's the problem?
Sounds like the alternator is bad. Did you change the battery because the light was already on? HTH. -Jim
Time to test the alternator.
Being in the business ,we often put in a New Battery that had a bad cell .. Take the car into a repair shop to see if he has a bad cell or something else is drawing the battery power ..
