I have been away from cars/trucks for the past twenty plus years. I was a gear head in high school and got side tracked with motorcycles ( Harleys). Just bought a 48 ford so here I am ready to jump in with both feet. This is a 6 volt pos. grnd car all original. So this is new old stuff. Never worked with pos grnd. systems but I am learning. Will probably ask some dumb questions. Please don't laugh too hard...
