Voltage Regulator

I hope I am in the right place. I have an 89 Jeep Wrangler with lots and lots of modifications. I bought as is so my project now. The Jeep has a 92 Jeep Cherokee engine in it, (242 MPI 4.0L MPFI), with that said the fuel injection was removed and made to a carburetor. The alternator that was on it when bought was on a homemade bracket, on the ac mount, that kept slipping and causing an incredible noise. I put a stock alternator on in the original location and adjusted with power steering point to tighten. It did the trick and no more noise. The new alternator is way different than the one that was there before. Reading this site it got me thinking on the voltage regulator and how to regulator the voltage to the battery. I saw a thread where someone took a Dodge Dakota regulator and wired it to the alternator and it did the trick. I am not sure if this meets my needs or if I need one at all. I am curious to what others can advise. I appreciate the help and be gentle it is my first time.

post a picture of the alternator, 1990 and older is a very different animal

An internally regulated alternator with serpentine pulley should work

The newer version of the alternator (what you installed) is externally regulated via the PCM (computer) in 92. Since youve got a carb setup, you will need to wire an external voltage regulator.

I went through a very similar issue. I believe the Dodge regulator fix should work for you since you have no computer CEL to worry about
