No - the CDI is AC powered - all the battery does is power the lights and run the starter motor
Whenever a no spark situation arises, disconnect the black wire with the white stripe at the CDI unit and check for spark - stil no spark, start troubleshooting the ignition system - stator, flywheel, CDI box , coil, spark plug cap and spark plug.
Thanks I will try that tomorrow. If that doesn’t work could it be the pick up coil as I replaced the coil, cdi, spark plug and spark plug cap Also should there be power coming from the yellow and black wire to coil
If you use a peak voltage tester, you should get about 100 volts from the CDI to the coil when the engine is cranking - the voltage cannot be tested with a standard multimeter as the 100 volt spike is only milliseconds in duration.
Regardless of how it looks, see if it will start - CDI spark is sharp and light blue - orange or white is bad and fat blue is associated with points and ICM's (Ignition Control Modules) not Capacitor Discharge Ignition.
