I drew up these diagrams based upon what s on my bike, and how I think it should be. I am wanting to convert the system to DC/battery power, and I already have a regulator and a rectifier, but I am wanting another opinion. This is how the system is right now: There is absolutely nothing wrong with it, it works perfectly fine, but I want to run HID lights which need a constant 12V power source, so that is why I am wanting to convert the system to DC then add in a battery. I think this is how it should all be wired up when done: The ground coming off of the lighting coil grounds onto the engine, which then grounds onto the frame, and then the ground is picked up again then ran to the headlight. I am thinking that if I run the frame ground to the rectifier, then I can run the DC ground to the battery, which then goes to the lights? The lights have their own separate wiring harness, they all work off of 2 wires running to then, nothing grounds to the frame.
