Are you sure we are talking about the CDI black box? The wires should all be going into a plug. The plug connects into the box, that's all there is to it. Please don't tell me the plug end has been clipped off of the wiring harness!!

Have Any pictures?

Get us some more info and I'll snap some pics from my service manual. You should get one!

Ok, there should be no way to hook it up wrong as it just plugs into the wiring harness.

No spark could be from a coil or stator problem.

Test the coil as per manual first and if ok then test the stator.

It does matter, the wires go into a plug, the plug goes into the CDI. Wires are supposed to be attatched to the plug.

Get a manual, look up stuff on YouTube and google it. Someone is bound to have delt with a problem like this. Tho as other have said there is very little to connecting a cdi box however one short or loose wire may cause havoc so I'd get a manual and read all about the wiring ( I'm assuming your relative mechanically minded )good luck

The stator generates the electrical energy to create the spark in the coil.
Get a manual and test the coil and the stator.

There are a whole bunch of lessons here. Getting an owners manual and a shop manual and becoming familiar with symptoms and how your rig is put together BEFORE IT BREAKS is very valuable. Then wou don't feel like so much like 157 does right now (frustrated, confused, and hoping and begging for answers in multiple posts). Instead you will have some reference material and likely can put a plan together so that you can at least start some diagnostics instead of sitting at the keyboard and imploring others to read the symptoms as you can word them and read your mind at the same time. Too late for 157, but if there is anyone else here that is "formative' in their riding and wrenching, today wouldnt be too early to obtain said references and start some studying. man will it save you time and MONEY. someday the time will be more important than the money if it isn't already.
