And on a diesel.....with glo-plugs. Wow!
I can remember my 1981 Bonneville with the 5.7L diesel (269,000 miles on that puppy) and its dual battery setup. One battery's positive cable went directly to the glo-plugs and the other battery's went to the starter. With a 22.5 to 1 compression ratio, there was a substantial current draw.
