Thanks guys, and thanks for the eplanation of the ground braid. I had a close look, and there was one connected to the ground braid, but the wire had been cut. I look around and saw no evidence of this wire anywhere else, so I have connected the loose wire in its place. machine fires up ok. I will have a play a little later tonight and will report back.

Thanks for the continued support and sorry for my ignorance.

I am learning heaps which is a plus.
