ah - good! Interestingly, it was this diagram that enabled me to properly get my head round the circling of F1-D and F2-D, both bypassed by the path of least resistance in the switch movements.
I think I may try something in a manual two pole (i.e. 1-0-2) dash charge switch so there is the full 3.0 resistance across the dynamo, and one side of the bypass switch as 'HIGH' with nothing, and one side with 0.5 ohm as 'MID'. I wonder if it's possible to get same chrome latching toggle switch as 0-1-2 so it is possible for it to be more intuitive.
