heh heh... good digging! But I have been hearing of the 48V system for a while. My dad also has some motors books with articles on it. There are some inherent issues with it though... not huge ones, but issues nonetheless. They talked about 36V for a short bit, then decided 48V would be the "standard". One thing to consider is that a 12V power source applied across your hands (one hand grounded), assuming 1500 ohms or so for the body comes out to about 8 mA, which is considered non-lethal for the most part. A 48V system is getting upward of 40mA, especially if you are sweating... a much more powerful punch. This means that more care and training will need to be happening regarding electrical system work on a car.
