Im working on an 87 YZ 125 which has no spark. Im having trouble figuring out exactly what is going on. I am getting voltage on the meter from the stator when I crank the engine and attach the meter leads to the brown stator wire on the connector and the ground. However, that is the only place im able to obtain voltage. So naturally I thought, ok the CDI is bad. I replaced it and still no spark. So I thought, ok its the ignition coil or plug wire -- Strike two. Still no spark. I also replaced the killswitch just to rule that out. No dice. What in the world could I be missing here? I cant seem to find any voltage coming out of the CDI. Ive tried to test every lead but nothing. I have the manual for the bike and I have attached the wiring diagram to this post (YZ125T). I have verified I have everything hooked up properly according to the diagram. Im at a loss here. Any ideas would be greatly appreciated!!!! By the way, if anyone is interested, I have a spare CDI, ignition coil/plug wire, and kill switch for an 87 125 now!!! Apparently they work fine!!
