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?

I have bought a non-starter Longjia LJ50QT-K in the hope I can get it running. Initial problem- NO SPARK.

Having looked at the Stator it was a right mess. no wires were attached, stator bolts were not tight and back plate was wrecked(this may not be the only issue, previous owner may have just given up and threw it back together?) so I have replaced it. Only thing is I couldn't find the right one for bike with the backplate in the timeframe I wanted, so I found this one here which is for the same engine but didn't list the LJ50QT-K. However it fitted correctly looked exactly the same and has the same wires that were on the old one. 3 Pin + 2 Wires(Blu/Wht & Blk).

Test done so far...(I'm jumping from car Battery- not started)

GND(Frame) to BLK/WHT wire in 2pin plug to CDI = Continuity when IGN off / No Continuty when IGN on (GOOD)
GND(Frame) to RED/BLK other wire 2pin plug to CDI from Stator = 0Vac when IGN on, and 80Vac when turning over engine
GND(Frame) to BLU/WHT wire (pickup) = 0.7Vac when turning over engine

is this correct so far? shouldn't i be getting 12v somewhere?

Help much appreciated.
