The reason for the question was that many coils I have seen have one wire connection going in and the HT lead coming out. The one coming in comes from the points (on older bikers) or the CDI on newer ones. if it is this wire that is being used for energising the relay then your relay will be opening and closing at many thousands of times per minute. They are generally not designed for this and will break sooner rather than later. A better nod would be to retrofit electronic ignition to a bike with points. You used to be able to buy kits for this quite cheaply.
