Here is the final outcome to the saga. I gave up trying to adjust the control box. No matter what I did, I could not stop it from suddenly flicking over to discharge, and there was no reliable charging with the headlights on. So I ordered a new box from Moss, which was broken when I unpacked it so there was a wait for a new one. This is on the car now. Yesterday on a 100 mile trip all seemed absolutely fine, so I started to relax - until the dynamo failed. I was 40 miles from home and got back on the battery - fortunately in daylight. As it happened I had a new one in stock so that went on. It has a damaged tacho drive connection which is why I hadn't used it yet. I now have charging off the scale at 30+ amps, and 25 amps with the headlights on. The old dynamo was too hot to touch and smelling of insulation, so I think the windings have had it.
I suppose the new control box made more demand on the dynamo - last straw and all that. Sadly I can't swap the end bearing housings as the new and old ones are different, so will have to work out how to repair the tacho drive sleeve.
