According to the vento diagram the headlights feed off of the stator on the green/red wire and is fused. JR So "B A" on the diagram means fuse? But I have only one fuse on the bike, the one coming off the battery. Are you saying I should add another one on the G/R?

D'OH! just so you know, I did have the key turned on when the fuse blew because I was checking to see if it would start with the button..well, i guess it's back to the drawing board..

ok, so I blew a fuse and went back over all my wiring. Then I checked to see if the turn signals worked--yes. the horn--yes. I wanted to see if the instrument panel was working to make sure I still have gas in the thing--yes. Now, the headlights are not connected to the bike anymore [wires not touching each other or anything else] but I turned the switch on anyway, mainly to see if I would get a good solid click, since I discovered that cracked piece when I opened the handlebar box. Sounded normal. Then I thought, may as well see if the High Beam Indicator light was working so I switched on the brights and pop! Blew the fuse again! It was then that I remembered that I had actually pressed that button earlier by accident but I had not heard the pop then, I just saw the fuse light on. Anyway, according to the Vento diagram, there are two wires directly involved with the high beams: the dark blue and the yellow/red. the dark blue is spliced between the two halves of the 9-pin connecting the instrument panel to the rest and the switch itself-- like a peace symbol, lol! The thing is, I can't get the darn switch box open to see if the connection is ok because somebody apparently loctited the two screws holding the box on the handlebar! I can't use a solder gun because it's plastic. I have tried PB. I have used an impact driver. I have yelled at it--it won't budge!

I followed your troubleshooting J.R.--got no spark even when I disconnected the kill switch wire. Thanks to your support I was able to summon up the courage to snip that red/black stator wire. I was nervous about doing it because the connectors were so close to the sleeves like I didn't have much wire to play with but I did it! Tried kick starting it again and after a few kicks, voila'! I couldn't believe my ears, turned it off and did it again and after a few kicks, once again, it started! Each time, it only ran a few seconds but that may be due to carb adjustments needed since I had removed it to clean it. I suspect the blue/white wire is not as good as it needs to be so I am going to snip it as well. When I cut the red/black wire, it didn't look all shiny coppery, really dull.. First, a trip to the Autozone is in order for some more solder and a better solder gun, then I am going to take Wang Chung out in the glorious N.C. sunshine and get him purring--I hope! Still won't start with the button, but Rome wasn't built in a day! I'll check back in later.. Thanks to everyone for their support! ;D

Ok, J.R., I set the multimeter on ohms and did test the wires: the kill switch dark green tested at 0.02. the ignition green tested 0.00 I have not tested from the kill switch to 9pin because, as previously posted, I found the plastic is cracked and I'm a little nervous about unscrewing it unless I'm prepared to address this..

Hey Junior! I would like to see how the CDI hooks up. Also, when I opened the handlebar to do the troubleshooting J.R. suggested, I saw there are two cracks on the piece that covers the kill switch wires! A friend of mine and I opened it before to check contacts and he had a devil of a time putting it back together so I am a little nervous about unscrewing it but obviously I will have to do something about the cracks, lol! Oh, and it gets better: I see what appears to be a tie cut-off at the edge of the light switch connections, between the metal piece and the wire! Been trying to get pics but it is so dark in there..

Also, what has me puzzled is: the CDI has a coupler with a black/white and a black. I know the black/white goes to the black/white on the coupler on the ignition coil end. BUT, since the coil is self-grounded, notwithstanding that it IS a good idea to ground it anyway, did the Chinese mean for there to be a black grounding wire coming from the coil to connect to the black on the CDI side, OR was the dark green wire supposed to go there? The plot thickens! I did not strip it down when I first got it so I really don't know everything the mechanic may have done. I DO know it left me stranded days after he worked on it and periodically ever since.

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.

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!

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

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.. Attachments:

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.
