here is a definition of a smart alternator (for those who are new to these over complicated vehicles),
Many modern vehicles adopted a load request type charging system with the introduction of smart charge systems and CANBUS systems which are now widely being used. These systems are controlled by the vehicle Engine Control Unit (ECU). As the vehicle demands more load the ECU sends a signal to the alternator requesting it to start charging. The alternator has to cope with varying electrical loads and adjust its charge rate accordingly. These days it is easy for these types of alternator to be mis-diagnosed faulty if a charging fault is experienced on the vehicle but more often than not, no fault is found with the alternator.
anyways All Nitro's have a generator and not an alternator (although it is commonly referred to as an alternator), with the voltage regulator intergrated into the PCM (commonly called the ECU),
so yep the Nitro does have a smart charge system (or smart alternator),
