Hi. 1985xl350r has a no spark condition. Pulse generator, coil, and armature all check out as per the manual. I installed a new cdi. I have voltage where i expect it and ground where i exoect it. The ignition switch abd kill seitch check out. Where dies the cdi get piwrr from? One lead of the pulse generator shows just over 500 ohms to ground. The other lead shows it is grounded. Is this correct? Any advice? Like to get this going soon. Thanks for your help.
