What ?? Nobody have any answers??? HUh..
OK. Heres the answer and its easy.. Just use a test light and hook the lead up to the positive side of the battery and then touch the other end on the top of the glow plug if it lights up the GP is good if it doesnt it needs to be replaced. Be sure to disconnect the GP lead first.
