1996 Vortec 7400 AD244 Install Notes
My 8 month old ACDelco reman CS144 (I think that's the OEM 454 one) went out on me this weekend. Pulled it off and found an ever-so-slightly bent shaft, bearings making pretty-pretty noises. Knew about this upgrade, so I went alternator shopping. I found Napa 1N-4807HO, which is a brand new 200A AD244 unit with a lifetime warranty. In their product notes they mentioned that it requires a cable upgrade kit, sold separately. I am not one to create a situation where if I do need to warranty it, they fail to honor it because I didn't install the cable upgrade. Holy crap, cable upgrade indeed; it is for the charging wire, and it is a nice heavy 2 Ga piece of work.
Easy-peasy, remove belt, unbolt old one, remove, remove rear support bracket and ready for new parts.
Now, the CS144 alt I had used the rectangular regulator plug, where-as the CS130 & AD244 uses the oval plug. I knew this going into it and therefore purchased the oval-style pigtail as well. Did not need to splice/solder anything as the metri-pack pins are the same, unpin old rectangular plug, pin on new oval plug. At this time I also included the voltage sensing circuit that mr98z71 mentions in his thread (HERE). I connected mine to the battery at this time, until I upgrade the crossover/feed to the fuse panel itself I'd rather not cook things. Using an '02 Escalade as my reference I looked at the wiring diagram for the alternator and found that the AD244 uses both the L and the I or F pins (seen it referenced by either letter). L is the brown wire that is the charge light indicator, I/F pin is the field engage/excite circuit. For reference, both are ECM driven on the Escalade. (great, when I do my 0411 swap I'll be sure to include them) I left the brown wire circuit alone, but I added the I/F circuit and tied it into switched power at the fuse panel. Did you need to do this? I don't know, but I did. Now, pictures...
New parts.

Cable kit has inline fuse holder identical to the one GM used on GMT-400s with heated seats (including Escalade/Denali) and similar to ones on S-series (98/99+, under battery).

I've got a question for anyone that has dual batteries that has done this swap. When I got the cable upgrade kit from NAPA they didn't show one for trucks with dual batteries. I'm sure it's not a huge difference but I don't want the driver's side battery seeing a slightly lower voltage than the passenger side battery and setting me up for miss matching my batteries. Anybody with dual batteries swap out the cable across the top of the fan shroud for a bigger cable? ... Appreciate feed back from the forum, and thanks to everyone for sharing!
Did GM change the plug on the alternators from 96-99? Some have said that this was a plug and play while others say it wasnt. I have a 98 which has a the white oval plug with one brown wire.
I just found out that the AD244 will have the correct plug for my model year. FWIW, the AcDelco part number for the 145A upgraded alt is ACDelco 321-2128
