I am talking about the power adapter for the newer iBooks and G4 PowerBooks. My last 2 have split enough to start sparking right where the wire goes into the adapter that plugs into the power port on the laptop. It still works fine, but can spark at times because of the exposed wire. Do you think it is safe to just get some electrical tape on there? They are $80 new and there aren't many OEM ones on eBay.
