Hi
I want to check my exciter coil peak voltage, but it isnt in the service manual. Who knows, what is the minimum peak voltage on the exciter coil ? I measured coil resistance, it was ok, but stator can be bad, if the ohm is ok. I have very weak spark, I tried with an other cdi , same result.
the R service manual writes minimum 50 volts, but it has a different type stator.
thanks
here is my bike

You will need to make yourself a peak voltage adapter if you wish to measure it with a multimeter.
A few dollares in parts, build a ful wave rectifying version, just goggle circuit diagrams for.

Pulse generator peak voltage 0.7v min (disconnected and while the engine is being cranked)

Exciters normally minimum 100 volts.

Hi
I measured the ignition pulse generator peak voltate ,too it was about 1 volt,that's ok, the exciter coil peak voltage was about 20 volts . I tought that is low. I did the measurements with an oscilloscope.
when I push the start button, I have weak spark, or no spark. I tried it an other CDI too, but the spark was very weak, the bike doesnt run.
Now one of my friend rewinding the exciter coil, I hope that it will solve the problem
