1987 Yfm 200 Moto4 Won't spark
 

Hello I bought a yfm 200 an it won't spark at all !Ive replace the ignition coil an for another Cdi box for it an I've got no spark "Could anyone help me figure out solutions how to get it running again ?Thank you


Also could anyone pm me or post a pic how the wiring diragram is supposed to be !Thanks

That also has a pull start, correct? ( I had an 86, it had recoil start and electric) if there is no spark with recoil or electric, check the obvious, like the kill switch, and the wiring, could be as simple as that. Even with a dead battery, the recoil should spark it. or, the key switch could be bad, can you get lights when you turn it on?

Yes,,But i use the electric start ! Well I think to have the headlight working the engine has to be running ?is that right ? Or should it get power from the battery ? I have the neutral light come on when I turn the key so I don't thing the switch is bad .

with an electric start quad, the lights work off the battery, if the neutral light comes on, your key switch is working, and your neutral switch is working, it wont electric start in gear unless the brakes are on. I would try the pull start and see if you get a spark, if not, check back on the kill switch, could be something is killing the spark. have you tried a new plug? i have seen old ones just go bad and not spark.
As for the wiring diagram, you can google that and get a printout right on your PC.

Ok (: Thank you so much sir ! Once I get home imma try to figure out the connections on my wiring because I unplugged them all an clean them for good connections an I'm thinking I have some hook up wrong if my headlight runs off my battery !I matched all the wires to the same color an there 2 black wires that are the same an i switch them around an I still get no spark !
