Its suppose to be 13.3v on the GS at idle. I was having a problem with idle too. Found that my throttle cable came loose

So i guess my new alternator that I got from ebay is bad?
the car runs with the battery disconnected but when reved and i let go of the throttle after reving a few times it dies

I'd never trust those ebay 'upgrade' alternators. I bought one out of curiosity. Took it to my buds alternator shop and miked it, wasnt doing anywhere near what it claims. Gotta use a smaller pulley that it comes with to achieve it. Did yours come with that extra smaller pulley?

No it didnt but, today I hooked up my wire for the Big 3 from the alternator to the batttery now I am getting 13.3v at idle, I dont know why I could not achieve it with the stock wiring though.
I never checked it before But I think this may have been the cause to all those dead batteries I have had
Im loving the Kinetic though
