I have been using my atv most of the day and I started it up and it almost immediately died. Turn the key on and the netrual safety light comes on, but it will not turn over or even click when you push the start button. So I crossed it over at the relay and it will turn over, but it still will not start. I pulled the coil wire and when it's turning over I am not getting any fire. So my question is could this be a Cdi issue or is it something else?

 

My guess would be the kill wire circuit has come on, either simply because you nudged the kill switch (surprising how many Quads we get in as "none runners" to fix, that just need the kill switch putting into the run position), or one of the wires/components associated with the kill circuit has broken. There is also an ignition fuse, not sure if the neutral light still works if it blows, so worth checking if it is OK.

 

That would be my first guess as well. I just had to pull the switch apart on my Timberwolf for a similar issue. Opened it up, pulled the switch apart, cleaned up the contacts, reassembled, and it works great again.
