I have a Zox helmet with an electric shield. This weekends ride, I went through 3 cords alone. The original cords that came with the shield didn't last long. The Yamaha dealer in my area had gmax cords. (They still fit). Or maybe they don't? But they lose their connectivity or something, cause they don't work after a few times of connecting, and disconnecting when your on and off the sled. . So I'm wondering if anyone has a Zox helmet, and if you would know what cords work with it? I tried to find Zox specific cords, but I don't know if they sell them or what.
