Just the sort of thing I was wanting- thanks!

Or clip the ground lead to the probe tip, to get a slightly larger loop
without even having to break the probe?

Now, levels- I realise, as I've said before, that such a 'home-brew' won't
be calibrated, but can you give me an idea of how voltage level from this
arrangement will relate to emissions specs?

Thanks,
