Voltage regulator for 80/140 amp factory Bosch alternators

Voltage regulators ensure that the alternator outputs the needed amount of power as required by the vehicles electronics. When the battery is fully charged and few accessories are being used less power from the alternator is required. Conversely, when the battery is low and many accessories are required more power from the alternator is required. Generally speaking, an alternator is a very simple component. More times than not a faulty voltage regulator can be the reason why your BMW drains or does not fully charge it's battery. If the system is not maintaining between 13.8 and 14.2 volts you may have a bad voltage regulator.
