NON IGNITION ON YAMAHA XT125R

Sory I am not well in English

My son's bike is a 2006 Yamaha 125 R

It's have an ignition problem.

now we find any ignition same as magneto lighter on ignition coil's output end.But it isnt enough for ignition.

This bike have a digital speedometer,I think that,speedometer not sent impulse to cdi but I seen bikes some versions havent a digital speedometer.

for example Yamaha XTZ125 is same other parts.

I test new ignition coil and controlled clutch censor.

CDI positive pin ok,ignition positive pin ok.

How many volt on igniition col's login plug? and end plug?
