Hmm, electrics really aren't my thing and I'm really confused now.

Wouldn't the current flowing through the test meter complete the circuit and drop the voltage? And why does the positive terminal of my Midget's coil have 8v after the ballast resistor from a battery showing 12.6v when I'm connecting the same test meter to it?

I need to read up on low voltage electrics, methinks...

Oh, and I have now managed to check that I do have a spark and I've set the advance with a strobe by turning the engine over on the starter for a few seconds at a time (any longer might damage the new cam). I should be able to start the engine for the first time later this week once some cooling system parts have arrived from Canleys, which are essential as the motor has to run at 2,000rpm for twenty minutes immediately on start up to bed in the new camshaft.
