Well the journey home was uneventful.
I was concerned there may have been a short and I really don't like the un-fused ignition circuit, however I think the culprit is a newish battery master switch. Just touching it whilst in the "on" position is enough to cause an intermittent supply. This doesn't really explain what I thought I saw on the ammeter - maybe it was flicking between discharge (brakes lights on) and zero. Quite possible that I mis-read it in my haste to find a place to pull in - and the ammeter needle does have a bit of bounce to it which could have fooled me. That's what I'm hoping anyway! The ignition switch seems sound enough and wiring all looks tidy and intact.
I have a spare switch which I'll swap-over tomorrow.
Thank you again for the suggestions - excellent roadside assistance!
Peter.
