Maybe your stabiliser is faulty?

Hi Peter

Thanks for that.

Although I was aware it needed a voltage stabiliser, I did not appreciate it needed to be 10 volts. That will explain the over reading when I tested it direct from the battery.
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?
