NO SPARK 03 900 Carb...Stator????

[JSun]

Had to leave a sled out in the mountains in IP today. 03 900 was running great, and all of a sudden died. No spark. What else could it be besides the stator? Thanks for the help, hopefully we can get it out of the hills tomorrow.

Could be a coil, Could be ECU Could be a rubbed through wire grounding out somewhere.

It could be a lot of parts.

Like Rixster said, coil, CDI, ground wire. Also could be any number of things in the wiring harness, timing sensor, condenser/regulator for the exhaust valves, or just loose spark plug wires. If you've got one, take another sled with the same motor (or an 800 carb will do also) and start swapping parts until it fires. Then at least you know what the problem is.

Emergency shutdown switch? Unplug and try.

I had the same problem with my 900 and after checking everything I could think of I unplugged the handwarmers and it fired right up, plugged them back in and would not start. You wouldn't think that they would be related but that was my problem.

To eliminate all chassis wiring problems, you can unplug the 4 prong plug down near the stator. That will tell you if it's your kill switch, key, tss or any short in the chassis. If it does work, you will either have to choke the sled till it dies or pull off a spark plug cap. (Or just check for spark, not actually try to start the sled.)

spark

i had the same problem on a 1m 800 last week and it was the black wire for the coil was broke right next to the coil

Pulled the 4-prong plug and it started right up. Drove it out of the mountain. Thanks for the input though. Yesterday was an epic day in the powder in IP. Probably snowed 2ft up high...

That means you have a short somewhere between the four prong plug and your key switch, should be the purple wire that is the problem. The kill switch on the handle bars is wired straight to the CDI box. Good luck.
