Since there is DC current running through the frame, there is risk of a spark igniting the fuel vapors. How do I know this? a)This is why when you jumper a car, you connect red to red, and black to engine block or frame. b)This is why your self installed juiced up stereo shuts off if not properly grounded the the frame. (Theres no ground in your automobile, its just the black terminal of your battery is wired directly to your cars frame.) So now, what does that mean? You can actually have a fire even if the key is in the "accessories mode only" You must completely remove the key from the ignition to eliminate all danger of accidental fire. Cant believe im the only one to point this out.
