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 also had that issue and discovered that the plug wire between the coil and plug was bad.

JR.
Would I need to get special CDI made up for my wire sequence or can buy or plug in any any Chinese CDI suited for Chinese version linhai 250 - 300cc designed engines?
Assuming to my CDI is in fact DC, which I think it is!?
Any suggestions!?
8 pin CDI.

Ok I have to ask you, when you changed out the EFI did you in any way compromise or change the wiring to the TCI/DCI?
Let me study the diagram a little and if you did indeed change the wiring to the TCI and ran it from the stator and fed it AC then it's toast.
A good picture of the TCI with the wire plug and wire colors is needed if you can do that for me. I can figure out the pin configuration and go from there.

   JR, Negative. When I changed out the EFI system, I also removed the stock ECU. So there is new wiring loom and a new CDI. Factory have told me that I have CDI and that it is DC. all the wiring you see in photo and the complete wiring loom was sent to me by the factory, it was just a simple connect harness into CDI. There might just be slight possible chance that I of all my luck, received the lemon CDI. My ECU was a completely different wiring system, about 20+ more wires compared to the pictures you see above. ![]() ![]() |

Here is your CDI:
.ebay.com/itm/Original-Digital-Igniter-CDI-Linhai-Aeolus-Mainstree-260-300-Scooter-ATV-CUV-Par-/231103114267?pt=Motorcycles_Parts_Accessories&hash=item35ced1ac1b&vxp=mtr" rel="nofollow" target="_blank"> .ebay.com/itm/Original-Digital-Igniter-CDI-Linhai-Aeolus-Mainstree-260-300-Scooter-ATV-CUV-Par-/231103114267?pt=Motorcycles_Parts_Accessories&hash=item35ced1ac1b&vxp=mtr
Next question? The old set up had a relay mixed in with the starting circuit which sent voltage to the TCI and was part of the kill switch circuit. Did you eliminate this too?
Looking at your photo I can do a educated guess on each wire since you changed out the system. We now know black is ground.
The reason we must know the wires is to make sure all is well before we say you have a lemon CDI? Could be the coil? Did you get a new coil too? Scooter was running and you just got rid of EFI and such right?
So let's do a little tracing.
Black = ground Black/yellow = should go to coil
Now we have 3 wires left so let's do a test to find the engine kill wire. I'm going to say green/white but here's the test. Unplug the CDI harness plug from the CDI.
Put multi-meter to ohms setting and set it at the 200k setting. Put black lead on negative battery post. With key switch on and engine kill switch in run position put red meter lead on green/white wire.
If this is the engine kill wire you should get no resistance/continuity nothing. Then with the leads still hooked up put the engine kill switch in the off position, you should get full ohms resistance/continuity or if your meter has the audible tone function full tone as well as a reading.
Now put the engine kill switch back in the engine run position and turn the key switch off, if this is the engine kill wire and all is hooked up correctly you will again get full resistance/continuity and/or tone.
If this doesn't pan out we need to do the same test on the blue/white or red/white wire. Once we know the engine kill wire then we only need to establish we have 12Vdc to the CDI.
In fact we can do that first if you like? Set meter to 20Vdc + and put black lead on negative post of battery, turn key on and touch other lead to each wire, blue/white first, when you get a reading of 12Vdc+ then we will know that wire and eliminate it from our test.
Last wire to find is pulse feed wire from stator to CDI, I'm going to say red/white. Set meter to 200Vac and put black lead on negative post of battery. Put other lead on red/white wire and turn engine over and take reading, it will be low from 0.50 to 0.15 Vac.
There's also the possibility of this system being a system that when killing the engine just cuts power to the CDI?

Alleyoop,
What is this wire sequence and is it AC or DC?
What scoot is it out of?

Alleyoop, What is this wire sequence and is it AC or DC? What scoot is it out of? All 8-pin CDI's are DC. It actually came out of a linhai too.
