No Kidding! I'm lucky that I didn't get shocked touching the extension and arcing. I can't figure out why I didn't. It would've knocked my silly. I go back up to the house to get the wrenches for the battery and the wife says " Everrything all right out there?" I say ' yeah - great!" Teaches me to not have a beer in my hand when changing the oil. Still have dead dash lights though...
