I bought a non-running atv for the grand kids without any knowledge about these Chinese atv's or their safety switches. I'm hoping to find a wiring diagram that will show me all the safety switches so I can get this atv started. Something is still preventing the starter solenoid from engaging, spark plug from getting fire and stoplights from lighting with the brake applied. Bypassing a defective master cylinder stoplight switch isn't helping with any of these problems. I'm guessing it's another safety switch somewhere that I don't know about, possibly in the transmission. And the black wire leading to the CDI box doesn't show any voltage either. Can someone please help me with a wiring diagram for a 2008 SUNL 110cc atv with a 4-wire CDI box? I've seen wiring diagrams on here for 5 and 6-wire CDI boxes but none for a 4-wire CDI box. The stator seems to be good according to test procedures I've read on here for 5 and 6-wire CDI's. Any help would be greatly appreciated. Thank you, Larry C.
