So I get my lifan in. I'm ecstatic. The flywheel is at the machine shop getting lathed to accept the pull start cage and my custom FMF 1 inch exhaust is complete.

Only question I have left is about the coil wiring.

I understand how the stator and CDI are wired but the coil has me baffled.

There are TWO wires with the coil. One is green, one is black/green.

As a general rule green is always the earth ground. HOWEVER...on my coil the green wire goes into the coil while black/green wire go directly to the screw that hold it on?

That has me real confused. If I ground the green wire and then run the other wire to the CDI...which is grounded at the coil...HowTF will it spark?

My only guess is that the green wire from the coil goes to the green wire from the stator and the black/green from the coil(which is grounded by the screw) goes to the black/yellow of the CDI?

Please help...don't wanna fry any of this!

Thanks,

Jason

the more I read the more I think the factory worker who built this coil was having an off day. I'm almost certain that the trigger wire should be the wire going into the coil(mine is green) and the other that grounds to the post is the ground wire (mine is black/green)

Just doesn't make sense to have to grounds.

And this won't be the first time a company has sold me something with wiring reversed. Bought a trailer once that the brakes locked up immediately when I hooked it up to my truck. Checked my wiring OVER AND OVER AND OVER. the company swore it was my fault. After pulling apart their harness...their worker did in fact reverse a couple wires.

Still want to verify with someone though.

Here you go.

just wanted to add a pic for clarification.

See how the wire that goes inside is green(normally ground) and the the other wire(black/green) connects to ground.

I'm confused.

Oh yeah...a Mikuni 22mm carb comes no where CLOSE to fitting with the tank unmodded. I'm about to cut and reweld the tank I think.

even with the turned out intake? I havent had an issue with the 22mm and fitment

lemme guess...the intake is too tall?

Intake problem has already been fixed. Just cut/rewelded the intake. 22mm Mikuni fits perfect under the gas tank.

Now then...those two diagrams don't help. I understand the wiring but I want to know why I will ground the green wire and the black/green wire is grounded too. Can anyone check their 125 Lifan and confirm their wiring???

Also...those diagrams have are for battery/starter lifans. I have a kick only lifan with no recitifier.

Anyway...here is picture of another lifan coil. Notice how the green wire goes to ground and the black/yellow goes inside the coil. Green is ground....black/yellow is trigger from the CDI as it should be.

Just ground the green wire and your good.

Okay...have you EVER seen this situation or do you know for certain.

IF I ground the green wire, AND AND AND I connect the black/green wire to the CDI WHICH is grounded at the post...WHAT fires the coil? Do you understand that in my mind the coil wire colors are reversed?

So you can, with 100% certainty, that my coil wiring colors are correct and two grounded wire will make my setup spark? That makes no sense. A coil needs a ground and a wire to trigger the interference to produce the spark:

Here's the problem with my coil:

I'm a master at wiring these bikes and can tell you for sure that the black/yellow is your coil wire and the green is the ground. Make sure the black/yellow is going to the coil and not to the ground lug. I always change the wiring because I make my own wire loom when I build the bikes from scratch.

Using your statement in bold above...PLEASE tell me how I send my Black/Green wire (NOT black/yellow like ALL labeled diagrams) is supposed to trigger the coil since it blatantly has a tab on it for the post?

Not trying to sound like a douche but I just don't see how two grounds equal a spark.

Well according to the pic the green is the coil wire and the black is ground which is crazy. I have never seen a coil like that all the ones that I have wired have a male spade that the black/yellow wire attaches to.

That's what I've been saying!!!

It's (_|_) backwards but if I wire according to the normal diagrams it WILL NOT spark. So now the question...should I wire like I know it should be or should I get a different coil?

Get another coil from Hooper Imports that way you know it's the right one.

great advice Scott (Gitrdone), one thing that you need to know is Scott has done his research on these motors and their electrical. Thanxs for the blue print as well, i am certain i will be referencing to that allot, come next month...
correct me if i am wrong but atc70.com (Sterdy) carries an intake that will fit the 20mm carb and clear the tank. PM tres for information...

Well until I showed that second picture...everyone was still telling me to connect the CDI to the black wire which would have fried my setup. There is not a single diagram on the internet that has my coils wiring schematic.

I'm new to ATC70s...but not to turnin a wrench...hell...my moped(79 Puch with a Polini kit), daily driver(79 Rabbit 20V, 263whp 13. 2 1/4), wife's car(Passat turbo) and other toys(ATV's mainly) all have work to em.

Never seen a coil like this one.

his vw's are pretty cool lol. glad everything got figured out though

Well it cranked up second kick...WITH the green wire going to the CDI and the and stator using the black/green wire as a ground!

So yeah...Mr or Mrs. Lifan factory worker was havin an off day.

Can't believe how quiet it is with the Banshee muffler. I love it!
