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, MeganHi, 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.
