OK so I have a big problem I keep killing alternators. I have killed 9 in 6 months. So far I replaced the exciter wire, postive battery cable. I am sick and tired of changing alternators what could be the problem. I was good for about 3 months with and orielly new alternator and a new exciter wire. I did a burnout 2 weeks ago and it died during that. I have noticed that with this new alternator that the alternator will die while at WOT but come back. I need to figure this out asap as I can't trust the car as of know. Thanks for the help somebody please help me out.

 

Do you have like a wrong sized pulley on there that your spinning it to fast and basically killing it?

 

no everything is stock setup. I am stumped at this.

 

Check your PowerSteering pump and hoses for leaks. My PS pressure hose was leaking on top of the alternator causing 4 of them to fry and I didn't realize it was the hose until it finally ruptured all over the alternator and the cars voltage dropped right after it happened...............

 

as Dmoney said check for a lead of powersteering fluid to the alternator first

I had that + my fix was a bigger alternator I think wich was from a 5.3 or 6.0 engine that the shop fixed slightly bigger but he made it fot and the problem was gone

I always had the amp drop to below 13 A after the car is warmed up or running for a while and hot untill he put that alternator.

 

Make sure that your battery is properly secured to the tray. I have seen loose batteries lean back and short out under hard acceleration. It could be grounding out and frying the alternator.
