I just got this bike and it needs to be rewired. I was going to buy a mag but the funds are low so I gotta use what I have for now and at least enjoy the rest of the riding season. I just need a simple wiring diagram for dummies. I'm only running a head and tailliight and a headlight switch, ignition switch and a brake light switch. About as simple as this system gets. Also has a generator, a bosch regulator and a battery. Any help would be great. Thanks.
