no not yet but i did change it with a used one that worked and i got a plug tester on the line and i also had a screw driver in my hand no bite and i know the wires going to it i tested them while turning the engine over nothing and i traced the wires back to the cdi the black /white which goes to the cdi and the black / blue which that comes from ignition and i can hear the relay click when i turn on the key and those two wires are dead but im getting power to the cdi on pin 10 which is green / black and as i said this is a new cdi theirs got to be another sensor that is sending a message not to fire but im not sure
