ok here we go, I have been trying to get my 1985 trx125 running and trying to diagnose the problem of no spark thanks to help from this forum. I have checked wiring at the cdi box and find that there is power coming in from the alternator, and at the blue/yellow wire from the pulse generator, there is no power coming out to the coil, the wire checks out fine with an ohmmeter. What should I have coming in from the green wire of the pulse generator and to the reverse switch? Since there is no power coming out to the coil is this indicating a bad cdi box? Help Please, and thank you in advance.

blue/yellow green/white 290-360 ohms on the pulse generator as far as i know

No voltage spec from the CDI box to the coil. If all else is good - put on a new CDI box.
