Always put negative probe on green wire or better yet a good frame/motor ground when testing the stator for ACV.

Alright so I tested the cdi and it looks to be ac. My battery was about dead so when I put the multimeter on acv and tried to crank it, it only read about 4ac volts per round. Read 0 dc volts when key was turnt. I put the negative point on the black/ground of the 2 pins and put the positive on the red/black side of the 2 pin cdi connection to the scoot. Problbly need a new stator because I put the blue ac cdi on and the plug had a small spark. When I put the weird stock cdi on, it had a regular spark though. Its very weird. Everything points to it being a ac scoot except the blue cdi not working. But it lights green when I try to crank. The light will still blink on a broken blue CDI, I have a broken blue one, it still blinks when the engine is cranked but won't do anything else really. Not to say yours is broken just pointing out it doesn't really help in diagnosing. Which wire read 4vac? The pickup wire that comes from the little box on the outside of the flywheel, or the red and black wire that is supposed to feed the cdi power? 4vac would be more than enough for the pickup, but extremely low for the cdi power |

The 4vac was coming from the red/black on the cdi. (power) I tried the negative point of the multimeter on the scoot chassis too, still said 0vdc. Would a broken dc cdi work like a ac cdi? I really need to trace all my wires, but I cant get a break with this weather and all. On the stock cdi, there is a red wire going to the starting relay. I guess for power. There is no probe on the red/black connection in the inside of the cdi. Was like this when I got it from somebody. I guess the stator was bad or something and couldnt make a voltage to the cdi so someone tried to make it work? Or, someone tried to make it so it wouldn't have a rev limit. Or the blue ac cdi I have is just DOA? i60.tinypic.com/2hgh7wm.jpgI have regular color wires on the cdi harness.? i58.tinypic.com/24cy4qt.jpg jerseyboy JR, alleyoop, Doug, JerryScript, skuttadawg, |

Trace all your wires and make yourself a nice little doodled diagram of the electrical system. It sort of looks like whoever worked on it before either didn't know a lot about electrical stuff, or knew something we don't. It looks like he tried to fix a broken probe by running a wire directly into it, but the wire is going to what now, or rather it is coming from what?
You've been having a lot of electrical issues and there's a lot of weird little things, maybe you should just rewire everything from scratch. You've already done a lot and rewiring everything from the beginning isn't really that hard, just make a before diagram and try to see what's wrong and maybe even simplify the circuits, then make an after draft and make sure everything looks good then do it and keep the draft for wire references.
Your scoot makes Frankenstein jealous. lol

The wire from the stock cdi is going to the solenoid. I talked about this in my other forum a little while ago. Nobody could understand what kind of cdi it was or how it sparked. Looks like a dc cdi, but It looks to be a ac system. Also looks like the red wire was made into the cdi. I'm considering redoing the electric work. The blue cdi and my wires are a good match right? i62.tinypic.com/nbeqtl.png |

That black CDI looks like a regular stock AC fired CDI, the red wire looks like it is going in at an angle to connect to where the red/blk wire is supposed to connect to. Where does that red wire come from, the stator coil? |

Its coming from the solenoid. Which part of the solenoid? One of the top large connections, or the middle smaller connection? |

Either way that doesn't sound right, especially if there is no probe on the CDI where the red/blk wire connects to. Is there any other wires connected to the solenoid? There should only be a thick red one coming from the battery, a black thin one that activates the solenoid, and another thick red one going to the electric starter motor.

It's connected by itself to the solenoid. When I got the scoot it was connected there by a naked wire wrapped around it, until I put a ring terminal on it.

I have to take a picture of it... I know when I redid the pwr wire, it was connected on...

Guess it's just cranking like there's no cdi hooked up... lain |

Try this; take the black/red wire out of the CDI wire harness by using a small flathead screwdriver to get in the tiny space in between the wire terminal and the harness and press in the pin and pull the wire out carefully, then wrap the wire coming out of the CDI around the terminal and electric tape it together real quick. Try to start it, see if anything has changed. This is where the cdi should be connected. You can also connect it to the stator where the black/red wire connects to the stator, in case of any weird wiring this would bypass it since it connects at the stator.
By the way, what is the volts coming out of the black/red wire when you crank?
I'm thinking there has got to be other wiring issues too, I don't think I've ever heard of anyone hooking anything else besides a stater to the solenoid, it outputs a lot of power to give to the starter motor, it's possible it may have already fried that CDI or maybe some other wires, you should look over all the wires.
