Hey thanks everyone for your replies. The cable for my wall charger is broken. ipod Charger is a brick/transformer that plugs directly into the wall w/ female adapter. I guess I will have to buy a new charger cable. I have extra iPod USB cables, I took one cable apart and it has red and black wires for voltage, 2 other wires for USB data. I'm not sure how signaling is done to start/stop charge, so I am not going to mess with it, but there was an article online about building a charger using USB cable.
