Here is a simplified version of the Jianshe 400cc CDI wiring which I found on Alibaba (submitted by a CDI vendor):

Attachment 6578

Hover or click on the thumbnail. For some reason lately though, I've had to right click on the thumbnail and select "open link in new tab" for it to work right. I don't know if this is a problem with my computer, or errors on this site.

Get out a meter and set it to measure DC volts on the 20 volt scale. Unplug the CDI. Turn on the ignition switch and set all kill switches to the "run" position. Measure the DC voltage between the red/white wire and the black wire on the CDI wire harness connector. You should see 12 volts. What do you measure?

Turn off the ignition, and set your meter to read resistance (ohms) on the the 2K ohm scale. Measure the resistance looking into the CDI connector again (CDI still unplugged) between the blue/red and green white wires. What do you measure? This is measuring the resistance of the stator trigger winding from the CDI connector back through the stator and all associated wiring.

Set your meter down to the lowest resistance scale you have (like 2 or 20 ohms - not "K Ohms", or "M Ohms"). Measure the resistance between the orange wire and black wire. What do you measure? This is measuring the resistance of the ignition coil primary from the CDI connector and all the associated wiring simultaneously.

Let's start here, and if everything looks good we can go on to measuring voltages while cranking the starter motor. If they don't look good then we zero in on the bad readings and dig deeper.

Remember that we're dealing with an intermittent, so you must start these tests with a non-sparking quad, do the tests, and then verify that the quad still has no spark when done. It does no good to collect data for a no-spark quad when it is producing spark...

Checked my cart nothing price 99.99. Next day 78.99 just happy that I hVe it running now.

I thought it was the battery possibly. But since replaced and can not get spark . Took off the plastic and again it fired up ..put it back to gather and no spark.replaced coil started to test cdi as per this post . I have different colour wiring but it looks to be same. 5 wire 6 pin type....

I'm a little confused that you say that the wire colors are different, but it looks to be the same... What? The test you quoted asked to look for voltages between wire colors - which you say don't match. Please explain. Perhaps you are using connector position instead of wire colors?






If you're using connector position instead of wire colors that seems like the 400c Jianshe quads above.





12 what? 12 ohms? 12 kiloOhms? 12 megohms? Those values range over a million to one. The test asked for a specific range to be selected, but you have an autoranging meter. That's OK, but once the meter settles to the best range you need to tell me what the range is. If you were to ask someone how much does that box weigh, and they replied "12", your automatic response would be: Twelve what? Grams? Ounces? Kilograms? Tons? I think you see what I mean...





Tyler I'm pretty sure your meter did not have the word "nothing" on its display. What do you mean by "nothing"? "Nothing" means different things to different people. Does "nothing" mean zero ohms? Or does "nothing" mean infinite ohms(i.e. open)? Or does "nothing" mean that you have no idea what you are looking at. Don't interpret the readings - let me do that. Just tell me exactly what you see on the display - and since your meter is auto ranging be sure to tell what the scale is that it settles on (which will usually be in small characters on the display).
