CS144 Alternator + Big 3 Wiring Upgrade

[mtbtim]

Hey My 3rd Gen 4runner Sisters and Brothers from another mother,
[MENTION=102606]infamousRNR[/MENTION] (aka Sean) and I have another Sic Mod for Y'all. If you're getting into wheeling or overlanding and you're starting to add more things that cause a draw on your electrical charging system, there's a couple mods you might want to consider. One is the CS144 Alternator Upgrade and the other is the Big 3 wiring Upgrade. And, lucky for you, this video shows you how to accomplish both.

Sic Mods and Happy Wrenching!

Nice vid guys!

Question about the CS144, I've read at least one post that recommends sourcing an alternator for a 1995 Cadillac DeVille with heated windshield.

While searching I find a few different models specifying with and without heated windshield.

With


Without


Why not just any CS144 140 AMP alternator?


EDIT
I ordered a New ACDelco Gold 335-1050 from Amazon. Cheaper than a rebuild at any partstore.

EDIT 2
Found this, as an option?
HIGH OUTPUT 140 AMP 1995-2004 TACOMA 3.4L 4 RUNNER ALTERNATOR

The one with a heated windshield has a higher amp rating due to the extra draw from the heater.

I used the heated windshield version on 96Red be using the same on the 01 when I get to it.

All of the CS144 alternators I saw listed for sale, regardless of heated windshield or not, claim to output 140 amps. Where is the variability?

Do you just insulate the three lugs, remove the wiring If the alternator came with it?

New DB Electrical ADR0211-250 Alternator For Cadillac Brougham 91 92 CS144 HO

This is a 250a CS144 HO. As long as it’s clocked the same this looks good. I’ll search for this specific Cadillac…..

120 amps according to Amazon.com: DB Electrical ADR0211 Alternator Compatible With/Replacement For Cadillac Brougham 91 92 5.7 5.7L / Chevy Chevrolet Caprice 1989-1993 4.3L 5.0L 5.7L / 10463120, 10463195, 10463204, 10463213, 10479855 : Automotive

Here's another option

HIGH OUTPUT 140 AMP 1995-2004 TACOMA 3.4L 4 RUNNER ALTERNATOR
Amazon.com: HIGH OUTPUT 140 AMP 1995-2004 TACOMA 3.4L 4 RUNNER ALTERNATOR : Automotive

The disadvantage is youd have to rebuild it if it fails or buy another one

I clipped and heat shrinked them back then 09. Figure you could use the leads as a power source if you dug into it.

Yea, I just ran that model and the autoparts stores have a 105a or 124a for the 350cid. Sorry.

I don't see much advantage going more than double the amps of the factory alternator, personally. 140 is fine for my purposes. I'm good with my Delco choice.

I agree and it’s OEM delco not hotrodded.

Just putting it out there.

So why go to CS144 Alternator when you have a Denso one?

Not sure if anyone is seeing this thread. But I have a question..

So I am trying to understand why would one go to the Delco CS144 140 Amp Alternator when Denso has a 150 Amp alternator that I would think would be a bolt on version?

The only minor thing on that would be that it will need a 3-to-4 pin alternator adapter.. But other than that IIRC you will not need to put any shims or washers to put it on the trucks.

Now if you really want lots of amps I would think going to a higher output CS144 makes sense.. but for the most part that might be overkill...dont you think?

Did you confirm that this denso actually fits? As I agree I rather have a denso than a Delco. Granted, I run stock. I just warn folks on the charging wire and make sure your circuits are fused properly with add ons.

Price is a big factor. I bought my CS144 for $140. Most DENSO high output alternators are $300+.

The other part is idle amps. The CS144 puts out way more amps at idle than the stock alternator. Many modified high-amp DENSO units put out the same amps at the stock unit at idle and are stated so by the companies.

You can do the pully mod as some members have done. Which will correct the idle no charge issues.

I just get a remfg or one out of the junk yard to rebuild...

Granted, most wouldn't do this. It's only an option.

I was only able to increase my 600rpm output by about 5a. It suites me though because I can now have my lights on with fogs and my heater on speed two or so and still maintain around 14v. LED brake lights helped free up some amps also.

I could always turn off my fogs because they pull 12a when on.

Winching CS144 Idle output shines and why I swapped, Big3 came later.
OE Heat output ALT would start to whine on a long pull, pulley swap not much better.
Haven't done 01 yet, CS144 Big3 hands down 1 n done.

All the high-amp Denso options use a larger body than fits on the 5vz. There is a 100 (or is it 110?) option from a Suzuki Grand Vitara that is a nearly bolt-on (drill one hole larger), but that's it.
