Odd alternator problem...
I noticed my battery light was on, so I checked the voltage. It was running at 12.02 volts, and dropping when I gave it gas. Obviously the alternator wasn't charging. I started checking the voltage on the alternator itself to make sure it wasn't a wiring issue, and noticed it would jump when I touched the post that comes off the alternator, where the wire attaches. There's something wrong with that post somehow, and it's making it charge at times and not at others. Have any of you ever had this happen? Any idea how to fix it? There's an 8mm nut that looks like it holds that post on, but I took it off and the post won't come off.
