2004 Buyang kids quad electrical nogo
So I was given a kids atv for my 7 year old for free if I can get it going, good deal right? I was told it needed a carb job and that was about it. So far i'm into it for about 8 hours, a new battery, a carb job, new throttle, new ignition. I tihought after i did all that it should fire up but that was not the case.
A little about the atv, i researched the vin and it says its a 2004 buyang kids atv. It has a foot brake only, it has 3 gears i believe but no clutch. It has a push button start and kill switch on the handle bar. It also had a 6 wire ignition which i replaced with a 4 wire ignition.
So the ignition was a 6 wire but from the research i've done the two extra wires ( Y and YW) i believe are headlight related so i put them on a toggle switch and hooked up the standard 4 ignition wires together. I have tested the ignition and it works i get power in and out like i'm supposed to with key in the on position. I have researched wiring diagrams for this model but the only one i can find that looks similar has a remote start function which this one doesn't have so its not really the same. I have put 12 volts to the starter solenoid and the starter motor turns over but there is no spark.
I feel like it was working before so its something easy. I don't really know much about 12volt electrical systems, I do have a multi meter for testing. I am hoping someone can point out some things to look for and how to test them and i can get this thing going. Any help would be appreciated!

Have you tryed it with the brake applied? Usually you have to have the brakes on for it to start. If that does not work try this. Their is usually a black /white stripe wire going into the cdi. Remove that wire from the plug. This will bypass all safety features. Try starting it you may have to hotwire starter as your bar control may be bad. If you still get no start or no spark then i would suspect your cdi is out. Hit up ebay they are cheap and get more than one so you have a back up. I bought 2 last time for under $20

I have tried with brake applied and nothing. I also did what you said and disconnected the black and white wire and put 12v to the starter, the starter motor kicked on but still no spark. Is it possible that i screwed up the cdi by hooking up the ignition incorrectly? I matched up the wires (black to black red to red etc) like I said I don't have a ton of experience with this type of electrical stuff.

So I traced some wires today... with the ignition on I get no voltage at the cdi at all which I thought was weird? I also traced the hot wire from the battery (red wire) it goes to the ignition but before it gets there it splits off and goes to the clip on the side of the motor (picture attached) which I'm told is to attach a battery charger? So after the ignition is switched on I get power out (black wire) which also splits with one wire going to the clip on the rectifier and the other going to the starter solenoid. Now with the one hot wire on the rectifier, if I disconnect the clip from the metal rectifier I get no voltage from the clip, but if I clip it back into the rectifier the voltage is there, it doesn't continue on to any of the other three wires on the rectifier however. The wire that goes to starter solenoid (black wire) and the other small wire on the solenoid have 12volts, the other wire (green and red) heads over to that same charging clip thing on the side of the motor.
Does any of this make sense?
