Sent an hour or so (at a safe distance!) with a neighbour who understands electrics much better than I. He quickly established that the field wiring in the dynamo is not functioning as it should. He traced it back to the switchboard & suggested that the switch was not feeding to the Field terminal on the dynamo and that the resistance between Winter & Summer settings was also not working.
This does not mean, he suggested, that the cut out may not also be faulty, but his tests indicated it was probably ok (as had my readings), The dynamo may be functioning since (as he opined) even with residual power at Field in the dynamo , as it speeds up it will, and appears to, generate some volts.
I had previously taken the Switch board apart & cleaned & reassembled it & it appeared to be working, but something is amiss.
Who is the "go to" person for checking/sorting switchboards? The warning lamp could also have a better connection than the one I have jury rigged!
