Need some help- got a no start  By  sickopsycho (Read 351 times)

I rode my bike on an errand today and when I came back to start it it would not start. I have no spark. I need to know how to check the stator, cdi and the coil (it has to be one of those). I had a spare cdi with me that was fine last time i used it- that didnt solve the problem so i'm not thinking it's that. I had a spare coil with me i tried replacing it- no luck. Not sure if it's good or not, thought it was but could be wrong. The only reason I question it is because I tested per instructions in the 139qmb manual and it tested bad (but then again BOTH coils tested the same). I ohmed out the two connectors (one green, one black) and got continuity with >1ohm resistance. The manual said this is good. I tested from the green lead (and the black) to the end where the spark plug goes and the manual said I should have gotten continuity but maybe 90ohms resistance. I got no continuity... suggesting a bad coil? Here is a pick from the manual explaining what I checked.

I also tried removing the black/white wire from my cdi which controls the kill switch, ign etc and still no spark so it's got to be in the ignition system, charging system or control (cdi).
I tried to check voltage going to the coil but didn't know what to look for. I set my meter on dc and got nothing when cranking to either black or green wire. Same result with AC. The primary culprit in my mind would be the stator. Not sure if the rectifier is in line between that and the cdi or coil... but I did have several headlight bulbs blow out before I said screw it and threw in a 904 automotive headlamp. Please let me know how I can check the stator (preferably without removing it as the bike is sitting somewhere I can't completely tear it down) or if you have any other ideas...
