Half marks - reversed.
1984-1986 XJ/MJ (and plenty of later Jeeps) used the Delco SI series - internal regulator.
1987-1990 XJ/MJ got the Delco CS130 - internal regulator.
1991-up Jeep (ChryCo-spec) used Nippondenso alternators - external regulator. Worse, if the regulator fails, it's not a standalone circuit, you'll have to replace the entire damned PCM (for, what $500?) to replace what should be a $20 standalone part (the voltage regulator.)
OK curious. Now ere on the subject. Will a cs130d work on the renix I got a low amp alt and it can't handle. The AC and regular. Night driving. Lights so I'm looking into a different. One. I need 110 amps atleast I may be pushing 85 right nowOriginally Posted by 5-90

You can get direct-fit OTS alternators for RENIX up through 100/105A, drop-in and go.Originally Posted by anothadayridin

I believe that come COTS CD130 units (I don't recall applications) run up around 120-125A, and the innards may be swapped (I also believe that the front housing carries the mounting tabs - so, just swap the fornt housing. All of the electronics are in the rear half anyhow.)
Any competent shop can upwind a Delco for you to 140-150A without a lot of trouble, it's a very common job.
I don't know if the CS130D will drop in in place of the CS130 mechanically - I'm fairly sure you'll have to adapt the wiring. However, the CDxxxD series is internally regulated, just as the CS-series and SI-Series. The latest Delco AD-series may also fit mechanically, but I'm sure it will need to be adapted (as far as wiring goes. I won't swear to a mechanical swap being direct, either.)
However, it should be noted that a number of people have swapped CS144 alternators in place of the CS130 with good results. The CS144 is somewhat larger (144m/m rotor, instead of 130m/m,) but it can be found readily in GM trucks of similar vintage, as well as GM full-size passenger cars with plenty of electrical accessories. Apologies, but I don't have an application list to hand, but searching up a combination of "RENIX" and "CS144" on various fori should prove informative.
