If I'm not mistaken, GM has had the voltage regulator internal to the alternator for years before '93.
The alternator has to be disassembled to repair the voltage regulator. Most do-it-yourselfers just replace the alternator.
Here's a picture that shows the regulator at RockAuto -
Jorge, You probably have an alternator on that truck,which means the regulator is built into it. Check the attached links,instruction and guides, Good luck

My confusion. Your previous post had me understanding you were saying the regulator was internal to the alternator. I have a 1999 Dakota and it has the internal regulator. I went back and looked at the wiring diagram for your model. The wiring diagram refers to your unit as a generator vice and alternator, and yes, it does get a controlling signal from the Power Control Module (PCM). It comes in on a dark green wire.
voltage regulator is located internally inside an alternator and is usually not a serviceable part. you would either need to replace entire alternator or take it to a alternator shop to have them replace the voltage regulator
The voltage regulator it in the ECM.What you need to do is go to the basic which can be overlooked like is the Alternator fuse burnt open that will require a new fuse, how is the battery terminal connection? You need to check that,Or how is the calbe from the alternator to the Battery is the connection in good shape? Those you need to check you mainly need a voltmeter to do this but a good visual inspection can get results,
The voltage regulator is inside of the alternator, it is an integral voltage regulator, so if the voltage regulator is faulty, the whole alternator needs to be replaced.
Well that's ABSOLUTELY NOT TRUE, the voltage regulator is in the ALTERNATOR. This vehicle needs an alternator and that should take care of this problem. Good luck and thanks for using FIX YA
