Simon, can you tell me about the signal sent to the ground of the coil please mate.


Is it


ground for ages, then pulse to break the ground, or is it nothing then quick bit of ground following by back to nothing?


As I think I may have misunderstood how this works, I was thinkig it was mainly in a ground state, but is that actually wrong and its mainly in an open circuit state and only flashes momentarily to ground?
