Trimming done!
Had another go at taking readings that looked pretty close to your suggested probable.
SO, back to real basics. I had a very close look at the dynamo terminals and one (larger dia) has a tiny letter D the other has an F. The wires coming out of the dynamo are slightly different thicknesses and the slightly thicker wire from D goes to the SH (and on to the cut out) and F goes to D+ on the switch board
I have a nasty feeling these should be reversed.......! Is F(ield) the same as SHunt? - and D the same as D(ynamo+) ??..........
As an aside, where the wires come out of the casing the "insulation" is totally carbonised and the wires look a bit tired, but use able. I will try & put a grommet of some sort to stop them chafing.
I hope nothing has cooked!
