    I just bought a non running sled with no spark. The top end was rebuilt with a 700. Supposably the original owner was riding it after rebuilt.now no spark when sold. What could this cause it to have no spark ? Coils ? Spark plugs ? Stator ? Mpem? Need some advice how to test it. Thanks guys

    Can anyone here help my diagnose a faulty stator? Mine seems to check out fine when tested with an OHM meter on the generator side but wont produce any light thru the lighting coil. Does the lighting coil have anything to do with igniting the generator? I had the sled running several times...
