It may be an internal regulator in the alternator. The engine computer is also the voltage regulator.

It is located on the firewall under the hood,if it is externally regulated. When looking you will find a ignition module,and a voltage regulator. This is a square shaped box,kinda small,(like a pack of smokes),and it should have a pigtail cord plugged into it.
the chiltons manual for my 1990 B150 dodge ram van states 80 inch pounds. For a Ram 2500 with 5.9L Cummins 12 valve engine. The torque should be 18ft-lbs or 24Nm.
If it is an A/T you add the same place you check it. If it is a Manual transmission, then you add lube under the vehicle on the upper side of the transmission.
