prior to '55 many car makers were positive ground. Studebaker, Nash Rambler and I think even Ford in the 30's. My memory is fooggy about who, but I clearly recall the fun when junping those old cars in cold weather.
my 37 "N" tractor is positive ground. Drives me nuts every time I take out or put in the battery.
A quick way to find out is to pick a terminal and take off the cable. If your wrench doesn't weld itself to the car's frame, then that terminal is the ground side.
