looking at connections will only tell you if they're hooked up, mechanically not electrically. Measure the electrical resistance of all the components when separated, then as you make each connection check for continuity of each connection with a volt -ohm meter or a test light(self powered), one by one as you go. make sure that the stator has good ground in the engine, the engine to the frame, & the coil on the frame. Check the spark plug cap-connector & wire to the coil, does it have some measure in ohms? By using the process of elimination effectively, you will find what is shorting to ground, what is not connected or the part that is not working, when isolated out of the entire system. good luck...
