Also I shorted the black/white stripe wire to ground. No spark!

 

My kazuma 110cc has this style CDI and coil. How would i wire them to this unit? or would it not be compatible with my stator. (if worse comes to worse) i found a replacement CDI like i have for $22 and 20$ for a used coil (correct one also) i am getting absolutly no spark whatsoever. but i AM getting voltage spikes when i crank at the orange wire going into the coil. is this a good indication that the coil is dead? i am getting no continuity between the spark plug wire and ground.

No continuity from the coil output (spark plug wire) to ground is not correct. That would indicate a bad coil. But make sure your meter is on a high enough scale to actually see the continuity. The coil output lead often has a resistor built into the output lead. On my coil it is around 8000 ohms. Some coils don't have one, in which case the secondary resistance will be much, much lower (but never zero ohms). The purpose of the resistor is to lower RF interference to radio reception around the vicinity of your quad.

There are still some unkowns whether your Kazuma CDI is compatible with the Monsoon CDI. It may work, and it may not. But it sure wouldn't hurt to try. If it were my quad I would do it in a heartbeat. Monsoon CDIs are hard to find.

I would replace the coil first (after double checking the secondary resistance measurement). Then if you change over the CDI wire the

1) AC ignition power to AC Ignition power
2) Trigger to Trigger
3) Ground to Ground
4) Ignition Coil Out to Ignition Coil Out

using this pinout on the Kazuma CDI:



That much is straight forward. The kill switch wiring is still up in the air. Right now the kill switch wire resistance to ground doesn't change when you turn the kill switches on or off. That's a problem we can address later. See if you can get spark first. See if the quad will run. On the Kazuma (generic) style CDI leaving the kill switch pin open enables spark.

Without a doubt we will be able to figure out how to wire in a switch to stop the quad.

 

So if I buy another monsoon coil would it be compatible with my cdi? I thought of rigging up the kazuma coil since its known to work but wasn't sure because it has two wires coming off of it.

 

So the black/red goes to ac power and the red/white to trigger ground to ground coil to Orange nothing to kill switch and I should get spark? I could just swap coil and cdi of kazuma since they are known to work. I'm assuming that the rest of the stator wires have to do with charging the battery so they can keep going where they were going.

 

The CDI and the ignition coil are tuned to each other. So when you substitute another design ignition coil it may or may not work. One of the nice things about most chinese quads is that the parts are often design copies of one another (which in turn are design copies of an old Honda design). They may look different on the outside, but *most* chinese quad parts are the same or very similar inside.

But I don't know about the monsoon CDIs or monsoon coils. They may be the same inside, or they may be similar enough in design to be compatible. Or not... But it is worth a try. I doubt anything will be damaged by trying - at least in the short term.

The most likely outcome of incompatible designs are weak spark, or no spark at all. There is also a possibility that the ignition timing may be different, but in that case the quad will run crappy (if it manages to start at all), so don't persist at driving a quad that's running terrible. Check the timing with a timing light if it runs, but runs awful.

Yes, wire the Kazuma CDI like you said and see if you get spark.

You can wire up the Kazuma coil too. Coils have three connections:

1) Ground. Sometimes this is made through the mounting bolts to the frame, and sometimes with a wire to frame ground.
2) Primary coil input (from the CDI Output).
3) Secondary Coil Output (thick cable to the spark plug)

 

What are the standard colors on a China cdi pigtail so I know what they are going to in the plug ?

 

I guess that begs the question "who's standard"...

Black/red is common for AC Ignition Power on a lot of quads.
Blue/white is common for the Timing/trigger pulse
Black/Yellow is common for the Ignition Coil Output
Black/White is common for Kill switch wiring.

It varies though.

Black is ground on some quads. Black is switched 12 volts on others. Green is almost always ground. Look at the picture of the 5 pin CDI above, and determine the wire color that ties to that pin. That is a better way to determine the function of each color wire.

 

Alright i wired in the Kazuma CDI and coil as follows


Black with Red stripe / AC Power (on cdi)

White with red stripe / Trigger (on cdi)

Ground / Ground (on cdi)

Orange / Coil (on cdi)



This got spark! and got it to sorta run! acted like float was stuck. I could spray starting fluid in and get it to stay running. So i pulled the carb and took it apart going to give it a good cleaning. Also replacing plug and fuel filter.

More wiring questions!

1 The carb has a electrical plug to the Enritchen (spelling?) jet. How do i wire this? does it get 12-volts WHILE cranking only?

2 Kill switch Can i just wire this to the old start button and make it GROUND the kill switch pin on CDI?

ALSO: Where can i get a kit for the carb? says "Champion" on it. Going to try to just clean it and put it back together first.

No idea if the charging end of things works yet but if worse comes to worse I'll just find a new kick start lever for it (missing)

Bottom line! you CAN wire a generic CDI and coil to a monsoon/yerfdog it 100% works and i highly recomend it instead of trying to find the wierd one that comes on it. NOT however sure if the monsoon coil is compatiable! I used the kazuma coil right off and didnt even try to wire the monsoon coil to the generic CDI

 

Awesome! This will help a lot of people with Monsoon ignition problems.

The Enrichener (Bystarter, electrics choke, etc) runs off 12 volts AC or DC. It is powered *continuously* whenever the engine is running. This powers a heater in the enrichener which closes off the extra fuel passage opened when the engine is cold.

The wiring diagram found in a link posted earlier in this thread shows the enrichener wired to one of the raw AC voltage outputs from the stator (a yellow/red wire according to the diagram). It also shows a resistor wired in parallel. Do you see a resistor on your quad? It would probably be about 1 inch long and 1/2 inch square cross section and mounted to the frame.

To kill the spark you need to ground the kill switch pin. Any switch will do. If you use the existing start button then you won't be able to use the same switch to enagage the starter motor. I would just add a new switch. BTW, there is high voltage on the kill switch pin and wiring while the engine is running. So don't go playing around with this wire with your fingers unless the engine is stopped.
