Whizzer MotorBike - No Spark - Help Requested

[JGC]

Still no spark.
I am using the GY6 trouble-shooting document as a guide.

My CDI has a different connector. See attached picture.

My key switch and the "Stop / Run" switch short to ground when either of them is in the off position


OHM Meter Readings:

CDI power winding - Black/Red to ground = 520 ohms

Sensor Lead - Blue/Yellow to ground = 110 ohms

Coil Primary - 0.3 ohms

Coil Secondary - 7,200 ohms


Voltages:

Tested by spinning the flywheel by hand with the plug out (no electric start) using Fluke DMM

Black/Red power wire - 18 VAC

Blue/Yellow Trigger wire - 0.1 VAC

CDI Output – coil not connected - 1.5 VAC

CDI Output - coil connected – 0.0 VAC

1. Am I better to buy a DC CDI and re-wire the bike?

2. Do the DC CDIs give stronger, more reliable spark?

3. Where can I buy a replacement AC CDI matching the one pictured?


Thanks in advance!

I am no wiz with Whizzers but that box and coil look like typical Chinese scooter ignition parts they come in two forms energy transfer (AC) and battery ignition (12V) check out Partsforscooters.com

I would buy a new cheap cdi n connect it just to make sure your not having issues with your cdi and worst case scenario is you'll have a spare cdi in your parts box and then you can rule out a cdi issue and move on from there if changing it out does not work. make sure your white wire isn't contacting any metal also unwire Killswitch n check for spark... http://www.bikeberry.com/?acc=87019fb492fe6f03c3bdb29cf2ffb6eb

Buy cheap cdi and connect it to rule out cdi issues and worst case scenario you'll have a spare cdi also make sure your white wire isn't contacting any metal and taped up as well as disconnecting the kill switch and checking for spark.... http://www.bikeberry.com/?acc=87019fb492fe6f03c3bdb29cf2ffb6eb
