theres only two wires comming out of the engine right? there shouldnt be any power between the two wires, one is power and the other is the ignition signal. the IRK earths through the engine itself (where the stock magneto has a green earth wire comming out to the cdi) so clip the test light to the engine or the frame if you werent already... but even if there you cant see any juice, wire up the CDI and kick her over before posting again
