Well, I pulled the alternator and cracked it open. Got the old voltage regulator out, but I'm still waiting on my new one to show up in the mail.

If anyone's interested in this, just let me know, I took a few pics.

It was fairly simple, albeit a knuckle busting, job. Plus, the space in there is so tight, that I had to squeeze the alternator past the air filter housing.

Thanks.
