Okay, new development...

I replaced all the fuses in my fuse box. With the car off, I read 12.2v on the battery. When idle, she drops to 11.4v. When revved, the highest she'll go is 11.84v. So the alternator is charging, but not NEARLY high enough. Bad alternator? I checked the brushes about 6 months ago, and they were okay. Should I check those first?

Thanks!
