Really odd electrical problem

[87AODGT]

Well, here's my problem. It just started while I was driving, and now any time the motor revs over 3000 the amp light will come on and the voltage will keep dropping unless I let off and let the revs drop under 3000. I have no idea where to start looking to fix this, I've got a year old PA performance alternator, new dyna batt from performance distributors, and a new starter from PA performance, someone's gotta be able to help

When mine did that the brushes were floating (I think) and the alternator quit charging at higher RPM, but it was a rebuild. I bought a new alternator and that fixed it. Doesn't the PA have a lifetime warranty? Give them a call.

Good Luck, Don
