i suspect it is the stator or the pickup/pulse coil that is bad. the first thing you need to do is rule the electrical components in or out. get yourself a good digital meter and do an ohms test on the pickup/source coil, the stator and the primary coil. clean off of the grounds and the mount for the primary coil. make sure the small black wire off of the black battery cable is making good connection with the harness. i assume the harness has power and the engine cranks with the button. i believe the orange wire you are talking about is pulsed 12 volts and triggers the primary coil to fire. i am not dead positive on that and keep meaning to check my self because it comes up a lot but i am pretty sure. it is possible that it could be constant and they switch the ground for the pulse but i doubt it and the problem has always ended up in the stator somewhere. cdi failure is pretty rare on a warrior unless someone has changed it out for one of the high rev boxes and used a Chinese knock off, those dont last very long. these machine are pretty well know for eating stators, my theory is they build a ton of heat and yamaha did not use a high enough temp wire and the heat breaks them down. the ones i have had to replace i have used rickystator units and it eliminated the problem
