I pulled the wires off the main harness. I now basically have only three wires, the rest aren't hooked up any longer.. They come out of the magneto, and they are black (or brown), red, and blue. How can I test the spark with just these 3 wires?? I know someone said hook up only the condensor and the points. I don't want to mess anything up though. I thought if I just take the red wire to the coil, and then ground the black wire, I can test for spark, but I am not sure if I'm right. Any tips on how to do this would be really appreciated. I've checked other posts and I just don't quite understand what they mean by just hook the condensor to the points. I don't know what a point looks like, and my wire coming off the condensor is white (or grey).
