I grabbed the manuals, thanks! The power switch is a bit sticky, so I need at least to try to fix that, so the service manual may help. > > seem to have the actual wires/probes.

Yes I do have the actual pods. They look like the picture in this listing (not the item I bought): http://www.ebay.co.uk/itm/152233591570 So, yes I have the pods, but no connectors > The probes/wires that go into those are totally passive just bits > of wire with grabber clips on the end.

I will buy a set and see how it goes. I also believe there are some probes that are designed to clip over a whole IC, any recommendations for those? I did try using one once but it was designed to be used in conjunction with grabber clips and it was so fiddly that I gave up, so I am wondering if there is something better.
