Testing 73 AT3 Generator / Stator

Greetings,

I recently picked up a fairly nice 73 AT3 125 and have been working to get it going with my one major obstacle at this point being no spark. This particular bike is the one with the electric start and generator (12V system), anyway I have managed to get all the lights and the electric starter working, but still zero spark. Does anyone know the procedure to determine if the generator is putting power out to the points? I initially thought the issue was a bad condensor, but I tried another with the same results. Any ideas anyone my have would be helpful.

Thanks,

Kevin Donovan
