The high voltage lead is not grounded in the coil at all, the current path is spark plug to coil to the other spark plug. I've also heard that the scavanging spark helps emissions slightly. A very big side benefit is that by using separate coils, the effective dwell, and consequently the amplitude of the spark, is increased. My motorcycle can run through a furious cloudburst and not sputter, although I do. mikey at trsvax 55, it's not even a good idea, it S*CKS!
