340 Chugging instead of Reving

I've found that with the extreme voltages were using, and improved quality of induction pick-ups, that if the timing lite pick-up is alongside or near other wires, it will trigger the light with multi strikes .

I found isolating the wire, or placing the induction pick-up away from other high-tension wire improves accuracy, reducing the number of false flashes.
Try it .

Good point. #3 wire has been within an inch from timing lite clip.
