Oh, and there was a little smoke coming from the negative battery terminal.
I think I'm going to get a new battery this week.
This sounds like a definite. Something develops corrosion that creates the lower voltage that when you crank burns off and lets the voltage come up a little. Where was the smoke coming from?
