Thought my new alt. went. The charge was in the red line. car was losng voltage as I drove down the road. Took it to autozone, they tested the alternator, it was perfect. They came out to my car with me to do some testing. half hour later and some cussing we found the positive terminal of the battery was hot, as he moved the wire the gauge jumped around, replaced the terminal bolts that go into the battery,tightened them good, now its above 14v 90% of the time, never, ever was the voltage so good and steady. I was so happy (except for freezing my a$$ off changing the bolts).

Well, glad you got that problem solved!

sometimes the issue is so freakin small its crazy!
Ive melted battery posts like that too!

yeah, we kept looking at the big problems like fuses, wiring, and the alt and overlooked the battery and terminals several times. When we found the problem we were like duh!
