Hi, Im new to the sledding scene, and i bought a hacked up 2001 thundercat motor in (i think) a 1999 chassis. It was cheap, and im a jeep technician, so i thought, how tough can it be? I have no spark on any of the 3 cylinders. I tested the crank/ign trigger with a multimeter. The spec on an arctic cat CD manual i bought says 101 ohms, and im getting 186 with the engine not being turned over. I havent tested the primary voltage from the stator, but im guessing its supposed to be around 80 volts. A Technician told me the stator is suspect, and usually you can smell it when it's burnt up. Has anyone experienced a problem of this nature? Are there any tricks to figure this out? Does anybody know the technical specs on the ignition parts? Please give me any tips you can, as i want to ride ASAP.

thanks

my skidoo did the same thing before i switched to A/C. here is a cheep trick to find out if it will run, follow the wires out of the engine and see where the cdi box is disconnect the one to the motor (some sleds you just have to disconnect the pig tail connecter) and see if it gets spark then if it does then one of the kill switched is bad then you just have to chase down which one it is by disconnecting the cdi box it will stop the grounding of the stater (you will not have head lights or any electrical while this is disconnected or any kill switchs) hope this will help, Megan

thanks for the tip meg, i have already bypassed the kill switch, and the machine still had no spark. I went through my manual and found a wiring diagram for the stator, and it gave me resistance values. all the values are within spec. should i lean towards the CDI box now? Are those a common item to fail?

any help is appreciated.

Try this,have someone push the throtle just a little or put a piece of tape to hold it,than pull rope to see if you have spark.The little teflon bushings on throtle ware out and won't allow carb saftey swithes to work.You can also bypass carb saftey switches if the $2 bushings don't do it.Also sometimes the tether don't push plunger in far enough,easy to check,just put something small in it to check.

He is talking about unplugging this pigtail,,, it will bypass EVERY switch on the machine to rule them out. If you unhook this and you still dont have spark, you are down to your stator (which is common on these sleds) your cdi, or you coils. I doubt its your coils as you have 2 and to have both of them go bad??? Try this first. I actually had nothing more than water build up in my pigtail and it caused the no spark issue. Pull it apart, check for spark,,,, if you have it, you know you have a bad connection (water) in your pigtail, or one switch on the sled is bad. Good Luck
