I did the swap on mine and it's great! But one question.

The wire that hooks up at the back of the alternator to the battery. The old SI one have like a plastic covet to avoid expose terminal. What's everybody doing to their CS?

Mine didn't come with the cover, and for now, I have electric tape wrap around to it. It's ok, but looks ugly.

Any suggestion?

Is there any other alternators with higher amperage output that will also bolt up.

FinallySS,

Try going yarding for one. I have a plastic cover on mine.

Other than? There are at least three aftermarket companies selling CS alts, and I think all of them offer them in higher amps. However, I think powermaster might be the only one with a 200 amp(?)

I have a cs series alternator. It's 185 amps. I think I purchased it off an ebay vendor called Load Boss Altenators. You can hear the difference when between being connected and disconnected. I never put an amp meter on it... but heck, if it runs more than 130 amps, Im good.

Pics??? I would love to see it. 185 amps is gonna build up a lot of heat...I'm curious to see how it sheds heat....I personally haven't had a reason to go over 140 amps but it is interesting nevertheless.

There's nothing different to see on the outside. It looks the same as the regular cs. It did come with a dyno sheet. The alternators from Advance come with a dyno sheet too. I know when you have it unplugged and plug it back in, it will change the idle of the car.

Serpentine. There are plenty of cars that used serpentine brackets. - Camaros, vettes, firebirds, trucks, s10's. The f-body works best. You should be able to pick them up from a salvage yard or ebay. I got mine from ebay and had them powder coated black.

I used my stock bracket. Just put the alternator in with the bolts loose and then tighten down on the bracket, it will fit.

I have V-belt too. What do you mean the ears are too big? What did it come off of? Mine came off of a Caprice with serpentine and I swapped my V-belt pulley onto it.

Hey i'll have to do this too, going from 13-14 volts down to 8 volts everytime its nighttime and i want to run the heat full blast is a real P.I.T.A., 84Supersport so you're saying I can just go get a caprice w/ serp setup alternator and swap pulleys? how hard is it to take the pulley off the old alternator and slap it on the new one?

Thats what I did. You will need to find someone who owns an impact and it will zip it right off. The pulleys were the same size also.

Has anyone been able to find the GM or Delco p/n's listed in the opening post? I had my dealer check today, both are discontinued and do not cross to anything current. I'm looking to do this swap but would rather have a harness I know will work than attempt to re-wire something and risk killing a new alternator.

Napa has them, I bought one last week. Give them the the GM or Delco part number and they can cross match it to their part number.

I bought my adapter harness at Napa. I cant remember though if the part number worked or if we had to look it up in one of their parts books. But I would try calling Napa.

Ok I've got the conversion harness and have tested it with a CS alternator so I'm good there. Problem is the alternator does not begin to fit the stock bracket.

In the original posters pictures, it's obvious the top alternator bracket is NOT a stock monte carlo item. I noticed his car is has TPI, possibly an F-body item? Now I'm looking for an alternator that WILL fit the stock bracketry OR the correct bracket to make the 10463338 p/n fit correctly. Not going to serpentine belt just yet either, long story.

It is possible to use the stock alternator bracket, however the spacer on the long bolt that goes between the alternator and the block is bolted to the stock alternator. You will have to unbolt it. It will not bolt to the CS style alternator, so just slip it over the long bolt. Also note that the upper bracket will have to be unbolted from the intake manifold. The CS alternator is larger that the SI, and you can't use the stock upper without unbolting it from the manifold. It may be possible to modify the bracket so that you can keep it bolted to the manifold, but I didn't bother trying and I'm satisfied with the tightness of the new alternator using the upper bracket without the manifold bolt. - BladeofAnduril27

Slotting the bracket hole where it attaches to the intake and washers under it and possibly re-angling the attachment point may get you the clearance needed from the stock bracket

If not this way then a custom bracket that comes up from the water pump, the lower bracket from the water pump to the lower hole and a rear bolt brace to the front of the exhaust manifold

EDIT: the OP's bracket is specific to 85/86 TPI cars and will not work on a carbed intake setup - he shows the difference between the two brackets in his first post on this thread

Hello all.
I'm located far away from the US, haven't got a Monte Carlo, but asking about the cs140, since I've seen, while googling, that the most serious answer was placed here.
My cs140 (1146-21) had only the F and L connectors.
I opened the connector, installing a sense wire also.
The vehicle that I'm installing the alternator is a 58 willys, which it's electrical system was built from scratch by me, and the 90Amp existing alternator has only sense wire, and a 'stupid lamp', the way you call it.

The question
Will it work with sense and L?
Should I put, in this kind of connecting, the 40ohms resistor, or it becomes unnecessary when using the Sense?

Thanks in advance.

You don't need the resistor wire when running the "stupid lamp" since the bulb creates all the resistance needed...

I think this may answer your question about the sense wire:
"Three-wire alternator. This is the most effective configuration. Essentially a closed loop "feed back" system. It uses a large battery wire, an ignition and or warning light connection and a voltage sensing wire. The advantages are a) the regulator is activated by the ignition/warning light wire, b) the sense wire, connected directly to the battery, continuously tells the voltage regulator the charge condition of the battery. (this information is significantly more accurate when sourced directly at the battery.) The voltage regulator infinitely varies the alternator output based on this information. No other configuration charges the battery as effectively."

thank you.

something is not clear enough for me - why, in that case, many Gm vehicles does not use the sense wire? it is so simple. and the 'voltage' is already an inch away (at the batery conection). so using the sense connection should have been the simplest, and the cheapest.
although - they (GM) didn't use it.

anyone knows the answer?
