I see this as an absolute win. Be careful, folks. Just because it’s DC doesn’t mean it won’t cause serious damage.

Edit for Clarification: When done correctly, the batteries should not arc. My problem is I did not wire the array correctly the first and a-hem second times. It only cost me one battery, which is a lot cheaper than a trip to an American ER.

    The frame is already grounded negatively. so if you remove red and happen to touch red post while leaning on metal car you make a circuit. so you pull negative first so even if you touch red it can’t travel back to the battery
