My controller shuts off intermittently while im on my gixxer but it stays on while riding the fjr. I thought this was a connection problem but thats interesting what Ashe said about voltage. I hate the gloves, i remember my thumb being freezing, id try to push it up against the grip warmers. They're bulky, my hands sweat but aren't warm, and I can barely feel heat from them on high.
However I love the vest. It has kept me cozy on many cold cold days. If i had to do it again I prolly would go with another brand. Oh and if you have both vest and gloves on the wiring is a mess.
