I just got a DB Electric Alternator from Amazon, ordered it Friday....it came late in the day Saturday while I was waiting to watch Mike Tyson (which was fun, guy is still entertaining). $91 for a new build, we'll see if it lasts, but that's pretty good.
I put it on...and runs quiet (huge difference) my OEM charges fine but was super squeaky. I'm actually keeping it for a "just in case" something happens and I can throw it on in a pinch.
