Will the alt produce any voltage if you increase the engine RPM to 2000 or 3000?

From the beginning both alternators worked fine, even at idle. I guess they lasted part of one stint each at the track when I realized they were no longer charging. You can wing it to six grand if you like...it aint happening. Something inside the alternator is just not holding up it's end of the bargain.
