NOTES.

The ignition circuit is a separate self-contained circuit with no fuses and no connection to the other electrical circuits on the vehicle. It has a separate charging coil in the stator (Green & White wires).
The ignition switch contacts are OPEN when the engine is RUNNING. Contacts are CLOSED when switch is turned OFF, this allows the system to discharge to earth. When fault finding, if there is no spark then check the "green" and "purple" wires to see if there is a "leak" to earth. Unplug stator & CDI, check green to earth: Ignition on = no continuity. Ignition off = continuity.
A "Resistor" type spark plug and a resistor plug cap should always be fitted.
This circuit does not require the engine to chassis earth. But if that earth lead is missing it is possible that trying to use the starter motor could force excess current through the CDI and damage it.

Always prove you have a good engine to chassis earth connection.
