So I had a look at the transformer in detail this morning. Since its open and therefore 'garbage' there is nothing to loose, right? Carefully peeling back the layers the first thing I found was that there is a copper outer shield to which that center bare wire is soldered. The two primary connections were below a further layer of wax coated insulation. The two wires coming in from outside are fairly thick, but the wires connecting from the coil are hair thin so great care was required when scraping back the layers and wax. The connecting wires are bent into a U shape and the wires from the coil seem to be feed into the top of the U and downwards. I couldn't see any solder so I assume they are just wrapped around each other, but I am not sure. I couldn't scrape away all of the wax along the length of the lead for fear of inadvertently cutting the delicate thin coil wire. I carefully added a bit of solder to the part of each lead that I could see to secure a good connection with the coil wire on both taps but unfortunately it still reads open. I therefore have to assume that the problem is deeper down in the layers of the coil somewhere. I don't know whether to risk going down any further as peeling back the next layer of wax and paper insulation risks damage to the coil, but it was at least worth a try to get to this point.
