[QUOTE="69ST, post: 20217, member: 5"] Since you should have a lot of years ahead of you tinkering with bikes, do yourself a big favor and learn the basics of bike wiring. Even the most complex wiring setup on these little bikes is pretty simple. When you break it down by system (CDI, regulator, lighting & ignition switch)the process of elmination will get you 80% of the way there. Things like ground leads, regulator connections, neutral light lead, lighting coil positive lead, primary coil lead and kill switch lead are easy to figure out. With those sorted, the only specific information that's indispensable are schematics for the CDI & ignition switch. In other words, it's only really confusing until you start tracing individual leads, armed with a schematic. Once you can recognize what all wiring setups have in common, you'll find that there's not much left to trace and, when you're only talking about 3 or 4 leads, the process of elimination oftentimes becomes a reliable helper. For example, all of your lighting should be powered directly from the battery; that eliminates any switching issues, including turn signals. All grounds, except for those controlled by the ignition switch are part of the same common ground bus. Regulator connections are pretty consistent, even with Chinese stuff. That just leaves your CDI, coil primary and ignition switch leads to figure out. Coil primary and kill leads are usually self-explanatory (and the neutral light lead is a no-brainer). Armed with the aforementioned schematics, that doesn't leave much to sort through does it? Kinda de-mystifies what initially seems overwhelmingly complex and, once you learn the basics, you won't sweat the wiring mods the next time you change engines.:) [/QUOTE]
