98 Ls1 Alternator Wiring Problem I have been looking on here for hours. everywhere i can think...i have seen every post by john...tried to email him ( but im west coast) can someone please help!!!!!
i wired a 470ohm resistor inline with the red lead wire from pin B on the alt plug to a switched 12v source.. i also have the + bat cable on the bottom of the alt going to the battery. i have tried multiple resistors (i have a 5pack) i have tried 3 different alternators...one orig and 2 new.....is it a possibility that when i asked for a 98camaro ls1 alternator at the part store...i was given a 99-02 alt??? i am pulling my hair out please help!!! AIM me at lexidrifts13!!!
thank u very much

Even if you were given a 99-02 f-body alt it would still work, the regulator is the same. The 98`s just run an external resistor while the 99+`s have the resistor inside the computer.
Did you have autozone check the alternators on their tester?
Maybe theres a bad ground connection?
If it is a f-body alt all it needs to function is ground, B+, the resistance wire to terminal B and to be spun by the engine.

Hi! thanks for the quick reply. i didnt have autozone check cuz they were new...didnt think i needed that. i have ground cables from engine to chasis...is that what u meant by grounding the alt?? everything else i did....help?
thanks again. IM me if u want! Alexis

You don`t need to have autozone check the alternators, but it would be something that is easy to do and will rule out the alternator as a problem.
Yep, I meant ground cables from the engine to the chassis and battery to chassis or engine. Also make sure that the connections are clean, corrosion can cause lots of electrical gremlins.

I was the one having the issues with the alt. my super caring girlfriend was helping me out because i didnt have internet access. after 2 days of messing around swapping alternators i found that the little 5 pack of resistors i was buying were not 470 ohm!! but 470k ohm!!! wtf im a idiot! put a new alt because i bought a lifetime warrenty bs one. and the damn things charges what do you know!!

Not to thread jack but while we are all here. I am doing an ls1 in my s-10 with the factory f-body alt and pcm controlling it. On my s-10 there is a brown wire that runs the battery lamp in the cluster does anyone which terminal in the alternator I can hook this wire into to keep the lamp functional? Right now it has the single red wire from the pcm that makes it all charge.

Kinda funny what problems a little letter like "k" can cause.
