I wrote:<<yesterday I was backing out of my driveway to jockey around my vehicles when on trying to restart... it wouldn't. Just a grunt like a nearly dead battery. Headlights are bright, so it isn't that. Battery treminals look clean like new. Tach spun 360 degrees counter clockwise when I cranked it. I didn't try beating my head on the steering wheel like Marty McFly. Any ideas? >> I neglected to add: tho I have an '82, I have the"Ducey goosey" alternator. Been charging just below the red line at about 10. Could that be it? Still, it came on me suddenly, no gradual pooping out of the cranking strength. -Wayne 11174
