"Remy" usually means "Delco-Remy" - or ACDelco, the GM Flagship brand. (Nothin' wrong with that!)
The most common Delco alternators in use are the SI series (early internally-regulated units, use two 1/4" spade-style quick-connects in a single plug for the "sense" leads) or the CS series (uses a funky version of a four-pole - 1x4 - Delphi Weatherpack for the "sense" leads.) There is a later "AD" series, but it hasn't been used in Jeeps.
The SI was never
used with the 6-242, although it was
used in Jeeps by AMC (after the Motorola alternator, starting ca. 1976-1978, I think.)
The CS series (specifically, the CS-130) was used with the 6-242 1987-1990 in the XJ and MJ. It was replaced for 1991 with the Nippondenso alternator in various sizes and outputs - and the regulator circuit was moved from within the alternator to the PCM (Powertrain Control Module.)
If you have a ZJ, as indicated in your profile, the Delco will not
be a direct swap for you - you have a Nippondenso. Assuming it's the 1995 ZJ, you should have the 90A Nippondenso - the later version will be a 117A (direct replacement, maybe with having to adapt the field coil terminals. 1999-up XJ w/4-150 or 6-242, 1997-1998 ZJ w/6-242 & optional heavy-duty 120A alternator, 1999-up TJ w/4-150 or 6-242: optional for 1999-2000, standard 2001-up.)
The 136A Nippondenso is also available to you, but it does require some grinding of the mounting area to make it fit (you end up having to remove about 1/4" of material from the engine bracketry - but that's not a big problem. It's because the armature is larger for the 136A unit.) Find this one in:
1997-1998 ZJ w/LA318 (optional)
1999-2004 WJ w/V8-287 (there is a Bosch version 1999-2000, watch for it. It won't fit readily.)
It is likely the connections for the field coil will have to be adapted here.
Again, I'm assuming it's the vehicle listed in your profile - even if you do fill out your profile, it is very helpful
to specify the vehicle you're working on in your initial post. Why? Some people are working on vehicles not their own, and some of us have rather more than one vehicle. And, I don't like assuming.
you fit a Delco into the 1991-up Jeeps? Sure! But:
- You have to find sense leads to plug in the internal regulator in the Delco, OR
- You have to have the Delco set up as a "one-wire/self-exciting" unit.
- You will
get a persistent CEL/MIL (I don't recall the code for ChryCo OBD-I or SAE OBD-II offhand, but it will be something like "Regulator Not Switching" - because the regulator circuit will no longer have any bearing on the alternator output, and the PCM will figure this out. It will throw a "hard" code at that point, and the presence of this code can and probably will
cause you to fail any periodic inspections to which you are subject - and it can mask other problems in the early stages anyhow, unless you make a habit of running a code scanner on your vehicle at regular intervals. This isn't a bad idea - not all OBD DTCs will trigger the CEL/MIL, which is why I plug in an OBD-II code reader on my wife's car - 2005 Verona - roughly quarterly. Haven't caught anything, but that just means I've wasted five minutes every three months. I can live with that.)
Is answer question? Is an orange?
