Your sparkplug coil(HTcoil) will have a black wire coming from it that plugs into the main harness up by the battery(male bullet connector). The wires from the stator assembly that plug into the main harness, one of them is black. Separate the stator plug from the main harness, then run the jumper wire to connect these two wires. This will totally bypass the wiring system. After completing this, check for spark at the plug. If the engine starts, you can kill the engine with the choke(unless its cold outside.lol). BTW, make sure the HTcoil mounts are grounding to the frame. Also, the engine mounts need to ground to the frame. BTW #2. Go ahead and check to see if the ignition switch itself is grounding to the frame. I just stick one lead onto the center of the switch and the other onto an engine mount bolt or rear shock mount.
