ECN Forum Forums General Topics of the Trade General Discussion Area Toner and Probe Wire Tracing Tips

I've got a ShortStop unit, but it does the same as toner, my question is do I have to have two open conductors for it to work, or tone, I. e. one hot conductor and do I need to separate my return/white and green bond metal jacket by removing leads and metal clad from panel box. seems to negate tone when I connect black lead to return white wire or can.
