Well ---12 volts is not used to make spark on this motor.----Check the kill switch.----Take ohm readings on the ignition charge coil and sensor coil.----Post your numbers.----How did the motor run for you last year ? ---What happened when you lost spark?---Is the battery in good shape ?---Have it load tested.----Pull starter apart for inspection.----If flywheel does not spin fast , there will be NO SPARK.

Also tested continuity on the 2 yellows coming from the stator they were good and testing the orange and brown wires from stator ohms were within spec

Finnaly figured out the problem ignition part of the stator is dead for anyone needing to test it put an ohm meter between the two brown wires coming from stator to power pack should have 50 ohms resistance
