I have a 2019 Ram Promaster 3500 Ext with the upgraded 220A alternator (sales code BAJ, Mopar part # 68271770AA.) I am using a Renogy 50A DC to DC Charge Controller and need to know if my alternator is Smart (variable voltage alternator) or a traditional alternator in order to properly install the Renogy DC to DC charger. No luck from RAM, Promaster, or Mopar in getting an answer.
