Great guide. It almost worked for me! I think I may have shorted the new battery during installation. Apparently, the battery has a fuse in that little circuit board to which the ribbon cable is attached (can anyone confirm that a short-circuit fuse is indeed present?). Anyways, I'm thinking of wiring in a temporary external battery just to test the iPod. Can anyone tell me which battery terminal on the iPod logic board is positive and which is negative? Thanks
