I've never seen a 7 pin CDI. So I'm not much help there.

How did the wiring harness burn up? The harness is supposed to be fused to prevent stuff like this. Where did you get a new harness?

For the CDI, have you tried here:

::: Katerra Motor Sports - ATV Quad and Motorcycles :::

I wonder if you can you get a wiring diagram from the above link if you ask them. A wiring diagram would be very helpful (as you already pointed out).

The remote/alarm, if it has or had one has about 7 different places to plug up stuff.

You know I hadn't thought of that ... But it doesn't add up after thinking about it. I've never seen a remote module on a 250cc machine (but I haven't seen a 7 wire CDI either!), plus I think this link shows a 7 wire CDI with colors that match as best I can tell with Harold51's post:

7 wire Double Plug CDI for JS250cc ATV [H048-031] - $49.95 : , Chinesemotoparts.com

Try as I might I could not find any wiring diagrams out there that show how this CDI is hooked up .

Yeah, I know. Who would put anyone on a 250 that needed a remote.

Because it has new wiring, I was just trying to stir the imagination.

Default Problems with 7 Wire CDI

HI, i have just bought a Bashan BS300S-18 engine and after many hours work have fitted it to my quad chassis. I bought a new CDI for the engine that matches the description of the CDI in this post. Despite having a wiring diagram for the BS300S-18 quad, i'm having trouble working out which cable goes to where, i.e. the wiring diagrams wire colors don't match the actual colors on the CDI unit. Did you find a wiring diagram for the CDI and a safe way for testing it? Any help would be appreciated! i've already melted one CDI and don't want to wreck another!
