No spark ec300 2006

[Sjoblom!]

Hi! I'm in a bit of hurry since I've signed up for a race this weekend.
During practice monday, it just died on me. No missfires,no hesitation before just completly died.
So, the spark is the issue. I started looking in to it yesterday. Wendt through all wireconnections, changed the plug, took the flywheel of and cleaned it.
No results, so i tried my friends ignition coil from a TM racing 250, and tadaa! Spark!
So i got a hold of a usel coil today. Mounted it, But Nope. No spark. Tried my friends TM coil again. No spark.

That tells me i probably have some wire that have gone bad somewhere. Right? Or could the cdi / stator flip out and internally have bad connection or something?

Electricals is'nt my best mechanic skill..
