Testing Stator?

My friends 05' RMK 800 lost spark the other day, it died while he was going somewhat slow on the trail then wouldn't restart. No spark on either plug wire. I swapped my coil onto his sled, still no spark. Disconnected the kill switch to eliminate that, no spark. Throttle lever free play seems correct to me.
Would a bad temp sensor completely kill spark? I thought it just retarded timing when out of spec.
Tomorrow I figured I'd try my CDI on his sled (I have an 04' 800). If that doesn't do it (and its my understanding that those don't go out as often as stators) how can I check to see if the stator is indeed bad?
Thanks in advance.
 
All measurements +/- 20%

YELLOW to BROWN= 0,15ohms
GREEN to BLACK/RED= 15ohms
GREEN to ground= open (no connection.)
GREEN to RED= 15ohms
WHITE to WHITE/RED= 185 ohms
Brown, check to ground (connection)
 
Tested each wire at the end of the wire harness coming from the stator. I think I have a ****ty multimeter and it doesn't read low levels of resistance well (I compared readings off my sled to my friends sled and all was the same except green & black/red). There is no continuity between the green and black/red wires. I suspect this is the power to the spark circuit in the CDI from the stator? Either way, sounds like its time for a flywheel puller and a new stator.
