    So I tried and the photo is what I had. One headlight hooked onto the first pole by itself to act as a low beam, and that worked fine. Then I split the wire from the first headlight along with the wire from the second and put them both on the second pole. The only issue i'm having is that when i put them both together on the second pole then both headlights light up no matter which position the switch is in. Granted neither headlight is grounded yet just wanted to see why that would happen. The way i have it wired now is just a rough job to figure out how to do it. Click image for larger version

            Yes. Thank you. I’ll have to get one of those diodes and give it a try. They eliminate the feedback of power?

                Alright guys prepare to laugh, I have a new problem on here. Any ideas as to why when I turn the key switch to off the bike continues running on its own? Would that be indicative of a faulty key switch or would something else cause this problem?

                  Sounds like you have 12V going to your coil/module all the time. Don't walk away from it like that, disconnect the battery. The coil will overheat if left connected and not running.

                    Assuming you don't have a magneto, the coil is getting power after he switch is turned off.
                    Use a test light on the coil to see what happens in all switch positions. If it never goes out then it is backfeeding somewhere, I'd think the lighting circuit is most likely. Remove the other wires one at a time until the culprit is located.
                    If it's a magneto then the magneto must be grounded to stop the spark. There's a terminal on the side of the magneto housing which should have a small brass grounding contact on it. Push that against the housing and it will stop.

                      I disconnected the battery after it did that. Won't reconnect it until i figure it out. Just never experienced that before. It started and shut off fine for a few days now it stays running.

                        I don't have lighting hooked up anywhere on the bike. Just started thinking about headlights but i need a diode that i don't have.

                          If you have an aftermarket ignition switch, it may have failed. Otherwise, you may have two connectors touching somewhere (like the back of the switch).

                            It's an aftermarket ignition switch. Might look into using the factory one and seeing if it does the same thing. I'll double check the connectors.
