Trouble was, when tested through the stabiliser I could not get any reading.
I've now checked the stabiliser and it does not work, so I'll order a solid state one from RS instead of the mickey mouse one Smiths supply which even has to be physically mounted vertically otherwise it does not work in its normal state!
Would one of these from RS be a better voltage regulator?

Hi Mike,
it was just a hunch. I hope it works better with the 10 volt supply.
Certainly an interesting voltage stabiliser that relies on gravity.
I think a solid state one that can supply all your instruments that need 10 volts is a nice idea, but it might be cheaper and quicker to get a new Smith's one. If you buy that RS component you will need to solder it on a piece of 'vero' board and add two bypass capacitors. Then mount it in a small box with some connectors to make it robust for a car environment.
Not impossible but I would just order a Smith's one from Merlin Motor sport.
