The XJ/MJ:
- 1984-1986 had the Delco SI (12SI, I believe) alternator
- 1987-1990 had the Delco CS130 (some 4-150 engines had the Delco CS121.)
- 1991-up got the Nippondenso.

The YJ got the Delco 12SI through 1990, went to the ND for 1991-up.
All TJ got the Nippondenso.
All ZJ got the Nippondenso (in two frame sizes, the V8s were slightly larger, since they had higher output.) Ditto the WJ and WK.

The Delco SI and CS series are both internally regulated, while all of the Nippondenso alternators used by ChryCo were externally regulated (with the regulator inbuilt into the PCM.)

They won't change over as a "drop-in swap" - using a Delco in place of the ND will throw a persistent code (since the PCM won't pick up on the field switching actually doing anything,) and swapping the Nippondenso in place of the Delco will require the addition of an external regulator (nearly any unit will work - many people use an early Chrysler external regulator, and the Prestolite marine-grade units are also quite common.)

Great write up Dirt!

There used to be a write up on this, on some Canadian website, but it disappeared from the internet. Que managed to copy it, and posted on a different thread. Maybe this will help with some questions, you guys planning to do this might have.

Wanted a few opinions on circuit breaker as I will be upgrading all my wiring associated with my 136A GC alternator. (Used 4AWG when installed). My plan is to very soon upgrade all my grounds to 1/0AWG, and use 2AWG for the leads along with some quality marine terminals and a marine grade circuit breaker in line. (I like this idea as a simple flick will reset the power engagement)

Wouldn't a 130A or 140A circuit breaker (or fuse, if you go this route) be more preferable than a 150A with the 136A alternator? Any explanations as to why or why not?

(p.s killer write up @DirtKar ...an oldie but a goodie)

Stop whining about the 'ride' - If your YJ ain't wrangling your soul free, then might I suggest you buy a stationwagon... at least you can fit all your bull**** in the back.

Bruin the circuit breaker is good on the individual circuit side but not on the main power side. Even having the right fuse is important. First thing, a circuit breaker is a fast acting device against an immediate condition. If you have too much current it opens. This isn't good for a battery line that is going to be dealing with the draw from a starter that cold can draw an inrush of several hundred amps. You need a slower acting circuit protection. If you even look at fuses there are some that are fast acting and some that are slow. Ive been trying to source a good battery terminal with the fuses built in. Many of the new vehicles are using them. They have multiple fuses and a larger fuse for the battery cable. If you are not changing the current draw from the PDC upgrading the wires to it is probably not necessary. Everything in the PDC is protected by the Maxy fuses on the input from the battery cable in the PDC.

In the future I will be adding a winch - later this year.

I just want to avoid a fire. You're saying a fuse would be best suited for this application? (i have x4 LED pods [low draw], x3 Hella 500 foggies [55W], and x6 LED rock lights [again, low draw]). The main purpose in all of this is to be prepared for future installation of auxilary electronics without having to re-address my wiring.

Then i guess my new question(s) becomes what would be a suitable circuit breaker amperage? OR, would a 140A fuse be better than a 150A fuse?

Yes A slow blow fuse is your best bet. A circuit breaker is totally wrong in this application. Worse case a breaker will fail closed when you need it. Go with a fuse. How are your lights fused and protected?

all my lights are relayed individually and fused through a jumpered switch panel.

Fair then... i will be going the fuse route. FOr the 136A alternator - what would be the ideal fuse amperage? I read somewhere 130-140A but was never explained why. Most of these write ups utilize a 150A.

WHich is best?

The fuse size depends on the wire size and current not on the device. Its to protect wires. 4ga. is rated at 135amps max but will deal with more current at shorter lengths so a 140/150 amp fuse works fine. You can google the wiring chart with the current capacity for DC voltages to determine what you should use.

Thanks for doing this. Answered my questions.

I wish every question was this easy to search and find an answer on! No search black hole tonight. Thank you again.

....so your saying you dont like 27 page threads whose original purpose was to discuss shackles - but leaves that discussion by page 8 unresolved and turns into a V8 swap? Also unresolved?

those are great. by the end of it, i feel like I was in an X-Files episode and do not even know how it all flowed right in front of me seamlessly without me realizing the transformation. Like a Pink Floyd song. Leaves me dumbfounded, deep in thought and needing more.
