Check the fuses on the passenger side kick panel instead of a voltage regulator idiots making these vehicles especially Ford and Dodge have the computer regulating the charge and from the alternator the current runs through your fuse panel before going to the computer if the fuse is blown your light will come on and the vehicle will not charge do not use a tester you must actually pull the fuses because you will get a reading on both sides of the fuse if it is inserted
