CDI Wiring By son10s (Read 13,630 times)

[son10s]

It is a 5-wire: a coupler with black/white and black, a red/black and blue/white to the stator, and a green wire. I know the black/white goes to the other end of the coupler black/white to connect the ignition coil and the black is in the coupler too--however, I know it is not required, since the coil is self-grounded. Moreover, the black just goes to a splice the last mechanic made so I can't tell if it was that way originally. the green coming from the cdi is the same color as the one going to the ignition but there was a dark green connected to it, possibly by accident when the mechanic disconnected the alarm and sent splices to a 9-pin. The dark green goes to the killswitch. There is a splice the same normal green as the one coming from the cdi end at the alarm 9-pin. Basically, I cannot tell which should be connected to the other end of the wires except for the ignition coil black/white and the two stator coils. Yes, I do have a multimeter.

GOOD ONE Son10s, MOTEL 6 WE WILL KEEP THE LIGHT ON FOR YA.

I have been playing around trying to convert .avi to .jpeg from the video I shot earlier since my camera won't do stills. I am posting this as a sample to see if it will work..

Well from your description sounds like the mechanic has made a mess? I want you to go to this link in the tech section and look at the diagram for the Vento Triton 4 and see if that looks similar to your scooter;

I'm printing it out to study and lets then talk about it.

Just put up the Video if you want to shorten the video MSN MOVIE MAKER to pick just the video parts you want to show. I use it all the time to shorten my videos.

Yes, it looks similar! Except I no longer have an alarm, just that 9-pin where the guy ran the wires into instead..

Here is where the alarm wires go.

my neighbor has the same scoot i will try to get some pics of the wiring in the morning to help

[son10s]

that would be FABULOUS!!! THANK YOU!!!

Can't keep my eyes open after staring at diagrams for hours, lol! Besides, I can take a better movie clip (to turn into pictures) in the light of day because the bike is in my living room.. Goodnight All!

Ha! I was pooped and blind from looking at the diagrams myself but I've got some questions and answers too because I have part of it figured out.

Now I wrote down the the wire colors you mentioned in the very opening paragraph that you said was the CDI and this diagram I mentioned is a perfect match so far.

You said you had a ohm meter and if you know how to use it then we can verify my findings very easy.

This is a odd setup but I've see worse!

Ok lets go to the CDI and the alarm plug, you said you had the following black/white, black,red/black,blue/white and green.

On the digram I listed above that's a perfect match as is the 9-pin alarm plug.

Now here is what we have, black/red and blue/white for sure go to the stator hookups, one for AC to the CDI the other for the pickup coil, done deal. The black/white goes to the coil done deal.

But now this is what is screwy. 99% of the scooters in the world use green for ground, NOT THIS BABY! BLACK IS GROUND!

So what is the green wire? It is the engine kill wire to the CDI.........and it goes to your alarm plug. Ah but the drama doesn't end there!

Alarms are just an extension of the igniton switch along with the turn siganl lights hooked up to a noisy horn but most of them when unhooked will leave you without a way to kill the engine! So what do ya do?

On your 9-pin alarm plug you should have a green and a dark green. The green again is the engine kill wire going to the CDI and the dark green goes to the igniton key switch.......and the emergency kill switch on the handle bar. This switch will also havve a black wire which again is ground. Your ignition key switch also has a black ground wire. When you press the switch you send the ground down through the dark/green to the alarm plug and if the alarm is plugged in then it will kill the engine. Same with the key switch, when you turn the key off you ground out the CDI through the black ground to the green on the CDI.

You alarm is unhooked, you must put a jumper from the greeen to the dark/green for this function to work. You can simply cut the wires and wire them together if you like.

Now we can easily verify this. I assume you have this scooter stripped and open for view? You can locate the CDI and find the green wire and the green wire on the alarm plug. Put the ohm meter probes on each end and if I am right you will get full ohms resistance.

Same with the dark/green, place the probe end on the dark/green at the alarm plug and then the other probe at the dark/green on the key switch and then try it on the dark/green on the emergency kill switch. You should get full ohms resistance at both locations. If this all checks out then again put the dark/green at the alarm plug andf the green at the same plug together.

Now if you don't know how to ohm a circuit if you can post a picture or a link of the face of your volt meter I can tell you how to do just such.

Let's take this from here and we will move on to each problem area and figure them out and get this baby on the road.

Now I take my grandkids to school around 7:30 and I work outside (weather permitting) during the day but I check in and out on the forum all day so I'll keep a watch on ya!

JR , to simplify things (you saw what I asked) going to a gy6 cdi will make it much easer in the future . I would like to see p/u pulse and 80-120vac , her cdi could be good . If the guy working on it knows the gy6 he may messed up the wiring and the secret is out from portions of the system .

[JR]

Well if you understand the system IMO not really John? The both still have the same operating procedure,

AC feed
Pick up sensor
kill wire
feed to coil
ground

Just a matter of knowing the wiring.

At this point until she answers on this I don't even know for sure if I'm on the right track here?

Good morning! Sounds like you have the gist of it--except the colors are opposite, dark green runs to the kill switch and regular green goes to the ignition switch. Regular green (henceforth, known as GREEN, I just didn't want to be inaccurate saying "light", lol) is the color coming from the CDI. When I traced the wires, it was a cobweb, so I had to remove connectors and disentangle them and that's when I saw what the guy did was splice off each wire to run to the 9pin. [On top of that, he spliced ALL the black wires but one step at a time, right?] But I was careful. As I traced each color, I drew on my legal pad and documented each connection I saw. When I got to the CDI, there was the green connected to the dark green and I stopped and thought, now that's odd. I'm used to seeing two shades with one having a stripe or two opposite colors but I have never seen just two solid of different shades with no stripe! So, when I trace this dark green, I find it going to the kill switch via coupling with a black/white and black and a splice going to the 9pin. I look for another green and find the only place on the bike is at the ignition switch. Now, I ask myself, why isn't there a connection for the green going to the CDI? Does the ignition need to communicate with the brain or not?
Btw, I have a Innova 3320 digital multimeter. This being the first one I have owned in my life, I have had difficulty reproducing various tests online--especially having no specs for my bike. I did manage to test my ignition coil, which turned out to be weak, so I replaced it and it tests good now.

ok i just took a couple shots of the nieghbor s bike i will have to talk with him to see if i can open it up to get more pics i think i have one of the reg/rectifier





let me know if i need to get more pics of this bike wiring
