Alternator regulators operate on the same principle as the original regulator, but in an intelligent way: they apply a charging cycle adapted to the service batteries. The external regulator takes into account the voltage of the service battery and controls the alternator's electro-magnet (rotor) to reduce or increase the alternator's output power, in order to obtain the right charge for the service battery.
These are connected in parallel with the existing alternator regulator. They act directly on the excitation current of the electromagnet, depending on the battery's state of charge. The alternator no longer operates at constant voltage, but in an IUoU cycle like shore power chargers, i.e. in boost, absorption and floating phases.
This type of regulator requires the alternator to be dismantled.
