Ponder This Dept...
Ford motorcars as far back as 3 cell batteries almost always corroded the positive terminal on the positive grounded battery. I thought this may disappear when Ford electrical systems changed polarity and voltage in 1956, but it didn't. Tar top batteries did not change things. Remember pennies stuck in the tar? The days of baking soda followed by a glob of grease. And all batteries were deep cycle. Kids. Park on a grade with a young lady turn on the radio listen to the vibrator when the tubes were warming up and silently curse as crashes of lighting static screwed up Fats Domino or Chuck Berry. While the positive cable slowly corroded.
