The spark plug is a good ground place, If it isn't grounding, you won't get any spark, either. Ensure your engine grounds are in place and good shape. You can run your multimeter between your sparkplug base and the negative post on your battery to ensure you've got a good ground. | |

I'm just a little confused what the difference between holding the end of the coil wire (1) near the engine itself and (2) onto a screw driver which again is held near a spark plug? When i tested the coil wire, i held it 1-2 mm away from a bolt on the engine which was not coated with paint. That is, clear metal (the bolt you see which has clear metal on the edges, the one you see just to the right of the lower spark plug). | |
