When you say it died, did the battery die because you mentioned you needed to charge it. Maybe it's not charging. Or just wont start back up because of no spark again.

* Topic moved to Yamaha forum and added ATV info into topic title.

Yeah it just died like I got no spark out of it so I replace the spark plug the plug wire in the coil there and I charge the battery hell I even hooked it up to jumper cables it turned over and started up ran great shut it down next day started it back up got halfway down the road and it died no again Spark. I recharge the battery and still nothing I don't know what to do I don't understand I would think if it was the pickup coil where the stator or the CDI it would die and not start back up again but it didn't start it it ran great and then shut down

I replaced ignition, coil and wire, starter silonoid, still no spark. I've cleaned stator, when I turn kill switch off it still turns over??? Not sure but I dont think that's supposed to happen .  

But would that cause no spark?

      1999 Yamaha Big Bear 350 4x4 no spark
      By Kaz
      Troubleshooting a no spark issue, was running OK, maybe a little rich, turned it off, now no spark. I've checked/ohmed out the main key switch, the start/stop switch, neutral switch, brake switch - all good. It will crank the starter, but no spark with the starter or when I try the pull start. I've checked all fuses and diodes. Swapped battery. New plug. New coil. Swapped in a used CDI - no help. Traced, removed, cleaned, reattached all grounds. Removed things like my winch from the circuits to be sure a bad relay or something was dragging it down. When testing voltages, the orange wire going from the CDI to the ignition coil shows no/very low voltage-shouldn't it have 12V on it? Sometimes I get a very weak, intermittent glow on my spark tester, but not enough to fire the plug. I've checked continuity on just about all wires in the harness. Checked/cleaned/lubed w dielectric grease- all connections, redid a few that looked old/dirty. I've checked the stator resistances, all good, but have a stator and rectifier ordered anyway, will arrive Sunday. I verified that the rectifier has a voltage output back to charge the battery while cranking - 10.5-11V, low, but expected while starter is engaged. What else can I check as part of troubleshooting? I have a Haines service manual, but the 1999 350 4x4 seems to be an odd model, there isn't an exact electrical diagram for it, but found one for another year that has all the same number of wires and same color wires, so I've referenced that. Any hints, tips or advice would be appreciated! Thanks!

      1987 Honda TRX250 No Crank
      By Arizona
      I recently bought a 87 TRX 250 not running of course, the owner had a brand new Key Switch on it.
      I think it is the wrong one or wrong wire colors as the colors dont match up with wiring diagram i downloaded for it. 
      anyone have a pic of their ign switch wires where they connect with the wire colors for that model? I ended up leaving the black/w stripe and
      green wire disconnected in order to hot wire it for other testing but would like to know as the colors dont match diagram.

      Need help! 1987 Yamaha Moto 4 350
      By P_syko
      I’m brand new to 4 wheelers and just bought a 1987 Yamaha Moto 4 350. It has good compression and fuel, but no spark. I’ve looked high and low trying to find how to test all the components of the ignition system, but can’t find anything. This has a new CDI box on it, but I suspect it might be the stator. How do I test the stator on this? Any help would be greatly appreciated!
