My friend's '99 zx9r has no power. It won't turn over at all. When he turns the key to 'on' his lights don't even come on. He recently got a new battery so what could be the problem besides the battery?
Make sure the battery is charged and filled, check the cables to make sure they are ok, and check the regulator/rectifier and the stator and the connections(probably going to need a multimeter for this).
Make sure to clean the batterie cables before you stick'm on the posts. And make sure they really are on the posts. if your not getting any lights the batteries either bad(no charge) or you hooked it up wrong (if it was the only thing you replaced).
