He has gone through 8 in 6 months. It only happens when he gets on it hard. It is a 2001 WS6 with the M6. Only mods are exhaust and a k&n besides that stock. Any ideas? I thought it would be wiring when he gets on it, it sends to much to the alt and burns it up but i would like some input before i start tearing into the wiring.

ive gone through 5 in 6 years, and i thought that was excessive. Its so bad that my front sway bar is off so i can swap it out in 6 minutes flat.

Yea that sounds like what he is gonna have to do. I just dont understand why its doing it. But i would rather have some input before i start going through wiring.

What brand of alternators you using?

Stock reman from Oreilly's.

Could be the quality of the part. To much power to the alt. isnt possible because its battery voltage, 12v when off 14.7 when on and the atlernators voltage regulator monitors and adjusts that. If any fluid is getting inside the alt it could cause one to short internaly. But more than likely its just part quality, went thru 4 autozone alts and then finally got a NAPA (when they still had good parts) and it outlasted the car

Advance Auto carries brand new Remy (as in Delco-Remy) alternators for less than $200, when my rebuilt alt failed that's what I got.

happened to me in the past and it was eather the power steering was leaking oil on it from above

and then even then the power was not ok after the car heats up a little

the fix was a truck alternator in place of it (the shop said it`s a bit bigger in size but he can fix it and the amp is more) and since then didn`t replacce it and always above 13 V on the dash

mine is a 98 Z28

just what happeneds with me and what was my fix maybe it`s useful for someone

it sounds like the exciter wire is messed up. It's the little plastic plug and small wire ontop of the alternator. its common that it happens, happened on mine and lost me 3 alts. Does his voltage drop to yellow when he goes full throttle?

its like 10 bucks and a pretty easy job since there's plenty of wire to splice into.

how many amps can the stock alternator handle?

i went thru 2 rebuilt ones from autozone in less than a week. everytime i got on it they would quit working. i ended up just buying a brand new one from Oreilly's and it has lasted for awhile now.

i went through 2 oreily rebuilts in 1 week. Bought from a local parts place and havent had the problem since. Also check the wire on top it may be broke inside the plug happen to me. easy fix

You have a exciter wire problem, my car did the same thing, it would be fine for a couple of weeks, then once you got on it hard instanlly you have a dead alt.

I bought a new plug and ran a new bigger gauge wire from the pcm to the alt and have not had another problem since.
I would give that a try I think it will take care of your problem.

Also make sure you don't have power steering fluid leaking into the alt either

Had the EXACT same problem. My shop replaced the wires in the harness from the ALT to the PCM, it did nothing. Then I replaced a really crappy ground strap from the block to the body, and the positive battery/alt/starter harness. I also redid the battery ground on the chassis side. That solved my problem. I don't know if it was the ground strap or the positive harness, or the battery ground. But it works now, PLENTY of high RPM runs, no dead alts. My money is on the ground strap....the old one nearly fell apart. But if you are trying not to kill another alt, I'd check everything.
