if u have got the volt driver, go to celestial archives and on the way up the platforms ( the ones that float in the air in the shape of a spiral) their will be a door node that can be destroid with the volt driver. keep going and there will be a yellow teleport.( you will be taken to transfer lock) destroy all the droids and gaurdians and shoot theese lights placed around the arena. then go to the center of the arena and scan visor the lock, this will make the teleport work. go out side and jump onto the moving platform that takes you to the far right platform.walk into the teleport. Right ,now the hard bit. go into morth ball and go to the top left of the room and keep pressing the bomb untill u get high enough so your on the platform. walk around the platform( not the center one) and jump down the hole. the shock coil should be right in front of you.

all confusing but good when u get it,
good luck,
;-)
