I've got a 1981 CT70 that is not producing any spark. I have replaced the spark plug, restored the stator using a kit to replace the points, coils, and condenser. I've tested the output from the stator using a test light and it lights up when I turn the motor over. I have also tested the ignition coil using a 6v power source and when doing this the bike produces spark. When hooking everything up it doesn't produce spark though. I've replaced the wiring harness and I'm still having this issue. I have even tried hooking up the output from the stator straight to the ignition coil and was still not able to produce any spark. I'm not quite sure what else to try and would appreciate any insights.
