Battery light coming on at high rpm

well that was just an assumption also, all i know is that i was told the only fix is new for these cars... that basically all remans do that and the original does too after it ages...

just a wild guess but simple physics involved couldnt you just swap the pulley for a slightly larger one to gently slow the revolutions on the alt at high rpms?? maybe one that is couple mm's larger not to slow it too much at low rpms but just enough to slow it so it doesnt reach its 'breaking' point before the car hits rev limiter??
 
Just what do you think they do when they "remanufacture" an alternator?

The old alternator is torn down to its constituent parts. The parts are inspected/tested and cleaned. Reman alternators are assembled from the old pieces (probably no reman ends up with any of the same pieces as before). Except for brushes and maybe bearings, the only new parts are to make up for shortfall when there are not enough old pieces. Occasionally, new or rebuilt rotors, stators, rectifier plates, or voltage regulators may be used.

Part of the process may include resurfacing the brush slip rings on the rotor. If it needs more than a gentle resurface, the entire rotor is usually scrapped.

Personally, I would rather go through my own alternator and actually replace it only if it needed expensive parts. You know its history (which you don't for the many components going into the reman).
 
i used to work for a place that did reman starters and we would test and repair what part was bad and look for anything else that was evidently bad and put back together with a cleaned and painted case and packaged.... so i would think that alts are done same way, and its some guy who makes $10 an hour and could give a crap less.. therefore prob not too many get done such a superb job as you believe... and someone should take the time to cross reference the alt to other cars and see if they redline in same rpm range and if they have the same probs... from my reading on here i see more of wiring prob with the charging system then alts being the prob in the end..
