Hi,

I have a M2R 125CC Pit bike, I put a new cdi on it (wiring look and box...). When i get the voltage from the red/black wire loom the stator it comes back around 15 volts on my multi-meter when I kick the engine. When i put the multi-meter on the black/orange and green wire which goes to the coil i get a voltage o negative -0.2??? and this is when im not kicking it etc. When i do kick it goes up to -2V...

Bike wont start and tried 2 different cdi boxes on it. Only difference was the the negative voltage is different between them
