The internal type of a BMW 525 alternator regulator is located within the alternator and in some cases is replaceable. To replace the BMW 525 regulator you must remove the power form the battery. The preferred way is to just remove the ground or negative battery cable prior to servicing the BMW 525 alternator or regulator. If the regulator is internal and is not removable, then the entire BMW 525 alternator assembly will need to be replaced.
