By the way, I never made myself clear in the first post.
My test light isnt a normal one with just a bulb in it, it has a bulb and a battery. One end is a pointer and the other a crocodile clip, when you touch the pointer with the crocodile clip the light comes on, which means a circuit is present.
here is a crude diagram of what I did, now shouldnt the light have come on?
Thank you
