fast answer, Needing high output alt GM kind easy swap

found locally a nice one! small an powerfull enough ( 85 amp )... fits on stock brackets and warning light equipped... CS-130D kind

just need to change the positive stud from diodes bank and is "doable"... plastic cover got the provision for that

AND... of course the pulley

checking the connections, what it says:

"PLIS-type

Mandatory connections:

1) Connect the alternator output terminal (B or Bat) to the electrical system's main distribution point (bus bar, junction, etc.) Less optimal alternatives that will work include connecting it to the battery + terminal or a terminal on the starter motor that also connects to the battery + terminal.

2) Connect the L terminal to a source of switched ignition power through an indicator lamp wired in series. Also connect a 50 Ohm resistor in parallel with the indicator lamp so that if the bulb burns out, the alternator will still be excited.

3) Connect the I terminal to a source of switched ignition power through a 50 Ohm resistor wired in series.

3) Ensure there is a good ground connection between the bare alternator case, the mounting bracketry and the engine block/heads and/or install a dedicated ground wire from the engine block to the alternator's ground terminal (if it has one).

Crucial connections:

4) Strictly speaking, the alternator will work with only the three wiring connections listed above, but I consider it crucial for good performance that you also wire up the remote voltage sensing terminal. To do this, connect the S terminal to the vehicle electrical system's main power distribution point (bus bar, main switch, fuse panel, etc.). If the S remote voltage sensing terminal is not connected, the voltage regulator will revert to internal sensing of the alternator output terminal voltage - with all the limitations that brings. You will see some alternators wired with a short jumper wire from the S terminal directly to the battery connection at the back of the alternators, but this is neither the proper method for remote voltage sensing nor necessary for internal sensing - do it properly or leave it out."

This alt I got is 3 pins ( no Phasing pin ) so despite this.

Then I have the L terminal runing to a LED on cluster on a vintage warning lights setup ( G indicator )

This will be the warning light and field at the same time... right ? ( I won't use the parallel resistor for it )



I terminal... ignition. Advices to use a 50 ohms reistor in series... HOWEVER, diagram shows a parallel ?

then the S terminal... which I would splice from same source the I terminal will be sourced


wondering why the 50 ohms resistor.

lot of ppl locally makes this job without any kind of resistor

I know is somekind a CHEBBBBBY stuff, but will great some opinions &/or guidance on this LOL

I have a cs130 off a 87 buick GN on my car.You will have to mod the spacer to the head and the adjuster bar will need to be ground to clear the alts fan on a big block. The resister has to be there or it wont charge, and some alts you will have to experiment with the resister ( 50 - 100 )ohms and if I remember correct 1 watt. Radio shack has them and you just solider them on the wire. I just have the s wire jumped to the big batt stud on the alt and the l term is the 12 volt ignition with the resister. When looking for cs130s you need to find the ones that have the mounting locations 180 apart. Also you will need a v belt pulley off a older gm alt as the buick and most of the cs130s come with a serp belt pulley.

is mandatory use the 1 watt one ?


I don't know. the worst case it wont charge. I think you can use a regular light but I am not sure if a led would work, the led may not have enough resistance.

led panel got resistors on each led for whatever reason ( under a shrinked tube... unkown resistance )

I asked to 12voltsguy.com thorugh an email, who is the "composer" of the article I posted the link. He didn't gave me a GREAT AND DEDICATED ANSWER BUT he told me, 1/4 watt resistors are used to cheat the flashers on led turn signals. I had to take my own conclusion with that anwers... so being these bulbs are originally 21 watts each, I think 1/4 watts should be enough then.
