mx5 console voltages

[Wain]

So i failed the IVA recently on a few minor points. One of the points is that the console back light and main beam symbol dont illuminate. The bulbs looks ok, i have swapped some over to no avail. According to the wiring diagram there is a red wire which goes from the light stalk to the console, when this is on it outputs 0.2volts. Is this the issue? Should this not be outputing 12volts? Can anyone confirm what voltage is passing to the main beam bulb on their console from a mx5??
