The day before we did jump another vehicle with the BMW. We used the special positive terminal located on the engine block but connected the negative jumper cable to a random nut on the strut (not the correct one as we read later in the manual). The car functioned fine the entire day but the next day the battery indicator light on the dash began appearing and flashing. There was also an audible hum with the radio on. Did the jump cause anything to fail? Is there a main fuse to the alternator that is possibly blown?
