I'm to the point of rewiring my 50 stude champion . The interior is 90% done, the painting is near done, motors half way back together blah, blah, blah...... I need to re wire before I put the rear bumper back on. And I think I will go o the 12 volt negative ground. My question is---On a 6 volt positive ground my entire car is energized right? So how come when the jack goes under the car-that is not a direct short?
Just curious----and no, I am not an electrician. I'm an HVAC guy.
