I understand you technique of testing to see if CDI is AC or DC. But I have a CDI that has pins 4 above 4 = 8 pin CDI.
I have 1 x black wire on bottom CDI
On the top I have......
Red/white top left, Blue/white to the right of that, Green/white next to it and yellow/black..
red/white seems to be stator negative
blue/white seems to be stator positive
green white seems to be linking brake leaver
yellow/black ignition coil feed. ( 12v power present with ignition on, engine not running )
Black seems to be 12v with ignition on ( engine not running )
Note: 12v tested using tester light.
It is Chinese version on yp250/Linhai. Make is Riya Adonis RY300T.
Is my version of CDI AC or DC?
