ELECTRICAL Condition: No Spark
Disconnect the single black (blackwhite) wire from the CDI Module to the ignition kill circuitDoes it have spark? Yes! No# Disconnect the stator to CDI module wiresTest the resistance values of the statorAre the resistance values within specs? Check the ignition switch, wire harness, throttle safety switches and kill switch for proper adjustment or short to groundRepair or replace as necessary
All except cylinders: If the parts of the ignition system under the flywheel check OK, the only remaining component is the coilCDI module assemblyReplace the module with another with the same CU number(See ignition data) All cylinders: Disconnect and check the secondary ignition coil resistancesRefer to the resistance values listed on IVa-10If the coil resistance values are within specs, replace the CDI module
Isolate which component's resistance is not within specsRemove the flywheel and statorRecheck the resistances; look for pinched or bare harness wires; or replace the stator
