Hi, wondering if I could get some help. I'm working on a Chinese quad (2010 Hisun HS400ATV) so let me know if you are unable to help me or I'm in the wrong spot. Basically, I have a very weird problem where my CDI has 10 wires, and only one of them I can reasonably assume is positive because it is red. I have the whole loom out of the bike so I have traced all of the wires from the CDI. the problem is, where the red wire goes is a 4 pin connector near the stator, but on the other side of the connector, there are only 2 (blue and black) which go into the stator housing. Wondering if you would know how to fix it or if I can just use another CDI I have (DC) and just wire it up to the battery. I thought I might be missing an exciter coil and that could be the problem, but only 5 wires come from the engine, and 3 of them are the reg/rec. This just seems weird though to have an AC CDI in a bike that cant power it. Thanks for your time!

Wiring:

Stator - (Black and Blue wire) - 4 pin connector - (2 white/green wires, 1 red wire, 1, red/white wire) - (Red to CDI, 2xW/G to CDI, and W/R to CDI)

I’d check the Hisun forum.

Thanks for the reply, I have the HS400ATV rather than the UTV (confusing, i know). I have looked over the ignition system on the manual I am using (for the ATV version) and I have possibly deduced an answer. My engine seems to be missing an exciter coil, whether it was never there or removed by someone I don't know. This is weird though because it has an AC CDI. So currently the CDI isn't even being powered. I acquired a DC CDI from a friend and was thinking about installing that temporarily to get it running so I can clean up the rest of it. What do you guys think about that? I would of course use the correct wires (12v from the battery, ign coil, kill switch, etc..). It does look reasonably factory considering the stator housing wiring seal has only 5 holes for the only 5 wires I have, plus the gasket looks factory as it matches one of the others (colour). I'm not sure what to do now in the way of getting the stock CDI running, I can test anything so let me know if you need more information. This would be really great as a learning experience if I could figure out the problem. I've heard that this bike is similar to the Yamaha Raptor 350, and by looking at the wiring diagram of that bike, it is indeed very similar. Thanks!

Thanks for the reply, the only one I could find related to Hisun ATVs was on quadcrazy, but looks largely inactive. I figure it is more of a general electrical question anyway but correct me if I'm wrong
