Hey, Jack, can I look at that diagram? Sabo, what they are trying to get across is that there is USUALLY a CDI and a separate regulator/rectifier. The two ground configuration that Jack mentioned is unusual to say the least so this will be fun. The carb? I'm afraid I'm going to toss to Alley and Jack on that, my experience with 2T is my weedeater and I hate it. It is evil. Please tell my wife I'm a funny man because she thinks I'm ridiculous. Hey Sabo.......
 Winky.
Also, you're a nice guy and you're very welcome. Rich
We are at the same side bro! My wife thinks the same about me  . Ok now about te carb. i have not given up yet and it also does not have many hopes the only thing i like to know about this carb. is how the electronic throttle works i test the wires came the there and, believe or not, have read no voltage so i presume he has drowning the scooter i can do a new 12v line to electronic throttle but it will work alone? About the CDI a JOG 50´s is the best choise but again is pain in head to find a new here...let´s see what happens and what the eletronics gurus have to say about that... Thanks, Sabotendar. |

Ok here the news: I do what Alley and Jhon says and test Black/Yellow wire turn on the key and start the engine and guess what? 12.5V~16.0V on that wire and multimeter set to DC so i test that fuse and he is good but the wires from fuse do not connect with CDI i not able to find continuit on any wire came from CDI with the key on or off position. On the great google i find a tutorial on how to test the ignition coil and more surprise! The ign. coil is broken too so i replace with one from Honda Biz 100 and test again now i have spark (a yellow spark) came from the new ign. coil so i think that damn CDI is good like lanternscooter say. All the tests i make with my old and broken carburator here some pics above, ok the engine has a strong smell of gas so i think the engine may be drowned by the faulty carburator, i open the air filter and guess what? NO FILTER inside this mess is become interesting ;-) So about the CDI, i have litle hope he has like the JOG 50´s but is the same problem to find a new one here in Brazil and the colors of wires has diferent. Here the link for one of that: produto.mercadolivre.com.br/MLB-546065648-m151-peca-yamaha-cy-50-jog-e-bws-cdi-original-_JM I can not be able to open the fan case because i arrive too late on my home but if your guys want i will open today when i come back to home. I not mention one thing! This scoot IS a Kasinski Prima 50cc here in Brazil but on the CVT case is marked whit HYOSUNG this helps whit anything? Here some pics:  "Maybe" a faulty carburator?  I open all the pices of he and clean but nothing happens here is the picture he after the cleanup process.  This is the faulty ign. coil and a faul spark plug too.  Just to complement: i put A new NGK spark, a new Ign. Coil and and a new battery but i want to change the CDI for a modern one anyway... Hey you are a funny man but my comunication with you guys is limited to my work, because my home PC is broken this end of week i will fix this :-) Today i will stay here until 16:00 PM. Guys do not now what to say to you about all support and antention that you give me on this journey...so i like say thanks one more time S2 |

I will do the test and post tomorrow, and see if that wire goes to the battery fuse...maybe a cracked wire? Even if the CDI is good I will exchange it for a modern one to be easy to replace it in the future  I will open the fan case and take some pics to clarify this enigma and let´s see what happens tomorrow... |

Well it's a DC CDI so with the KEY ON an NO BATTERY you will get NOTHING. So the First thing you need is a BATTERY otherwise that motor will never start or produce a Spark at the Spark Plug. That Black/Yellow coming from the IGNITION to the CDI should have 12v when the KEY IS ON and when you put in a BATTERY. Alleyoop With the new batery instaled and the key in ON POSITION i receive nothing on black/yellow wire, to test i place the red proof of multimeter on the terminal and the black proof of multimeter on chassis of scoot and the multimeter is set to resistence. When i back to home i will place the multimeter on DC marker and test to see, but to be honest i think i do this test before but i dont remember the result. |

This guy Pm'd me and ask me to look at this, I think the guys have it spot on so far. We've got to get some multimeter work on this to figure out what we're dealing with. I have some concerns that need to be cleared up.
1. Get a multimeter on that black wire from the ignition and turn on the key, if it's 12v DC we have a DC CDI system.
2. The way that is drawn it suggests a three phase stator but why are the wires different colors? Sabotendar, are those three wires bundled together in a connector? Do they all go to the rectifier? And just one wire comes off of the rectifier? You need to get us some pictures of these components. You drew a schematic and took a picture. Pull some plastic off of that bike and get us pictures of the wires and components like the rectifier, coil, the more the better. Then I want some meter testing which I will go over at that time.
 3. I'm guessing at this point but if the key grounds the #3 wire that's probably the kill. The odd thing is the systems that kill with the key through the CDI ground CUT the ground and kill the CDI. This one engages the ground which would suggest grounding the coil. Most DC CDI systems cut the DC power to the CDI which kills it. I'm just going to put that on the back burner until we can get some more data. 4. I know one....I know one!! That's the coil wire! 5,6. I gotta go with John on this one....huh? The way it's drawn I gotta say trigger wire(s). It is an AC feed so the current has to oscillate back and forth. But it usually just grounds to the case and then the CDI grounds and that's your other leg of the circuit. It is entirely feasible that you could run the AC trigger circuit right through the CDI, both legs connect to the CDI. I need some AC voltage readings on those wires, I can tell you how to do it. Now a modern CDI doesn't have those connectors so if that is the case we will run the trigger to the CDI, ground the CDI and make sure the trigger has a ground back to the CDI. You probably won't find that CDI or anything like it. We will have to figure out the wires and hard wire it. Oh boy! This sounds fun. At this point we need some pictures and meter readings. Let us know when you're ready. I did the tests checking the continuity of the electric circuit with a multimeter starting the from CDI connector to the stator and ignition key off from contact here some pictures:  Stator and pulse plug  CDI connections the colors came from CDI plug is not the same from from scoot circuit plug.   Stator and pulse coil plug.  Wires out from fan. The cables are dirty and after i make clean i have to make another schematics. all the tests are make with the engine not working and ignition key out from contact. I make a mistake from the frist schematics i make the tests with key on contact...so the reads have before with multimeter are wrong...  New schematics. Oh! dont know if the pulse coil have 2 wires out but judging by appearance of wires out from fan case i assume it is. |

The engine not working the carburator is missing and ill be replaced on the next week the battery is replaced and working. Soon i arrive on my home i will do the test and post a picture of stator plug. The scooter worked but when stopped working i dismounted and saw that all the wiring it is rotten and patched however worked anyway.
Thanks to all for the help...

Yea! Let´s see what happens, my stator and pulse coil is similar to this but te color do not match with i have here but the connections plugs is the same:   |

Hi, Here the schematics of the CDI on my scooter, he is a DC-CDI?  |

He use 2T oil on the gasoline mix so i think is a 2T engine (1e40QMB) the carburator and the automatic choke is broken too and i will replace with a new one with no automatic choke.  But i dont have any clue on how to replace the damm CDI since i cannot find the original in my country (Brazil). |

Hi guys, I´m loking for squematics or pinouts from this CDI he is not working anymore and i like to replace with another one is possible to place anoter compatible whit this CDI?   |
