There is a single dark wire which has a connection near the engine. It comes out of the stator along with a bundle of wires. By disconnecting that, you remove all switches which can kill the engine. If you have no spark with that disconnected, then you'll have isolated the trouble either to the stator coil or the CDI. If you do get spark by opening that wire, you'll know your trouble is in the wiring, (a ground short), or in one of the switches.
If the problem is at the engine, first try testing the wires coming from the stator coil where they are connected with the three-prong plug. You should not read "open" or "0" on any of them. Each pair of wires should have a resistance value between infinity and 0. If your readings are clearly bad there, the stator is your likely problem. If you get resistance values between 0 and infinity, it's more likely that your CDI is not functional.
