CDI – 2/4 coils, cables

[sx3-sweTopic starterBerichten: 290]

Hello,

I picked up this motor today with CDI, it has 4 coils, and 4 cables.. 3 for the CDI and 1 for rest electric.
But according to this diagram, the 4 coil cdi should have 6 cables?

Mine is more like the diagram for the 2-coil CDI system, with only 4 cables + ground connection

You can see pictures of my ignition below. What is the main difference, and why would it better to have 6 cables instead of 2?

Your icnition has: 1 coil for brake lichts. 1 for horn. 1 for icnition. 1for light.

And you have a cabel from the pick up. and for the zero pont (ground). That make,s 6 cabels.

Two coils would not be eunuf to power al the electra.

okey, but I only have 4 cables total, Green, Red, White, all of them goes to CDI unit.
Then I have only 1 left, which is 1 cable shoe in plastic housing, + ground attached to the carter..
So 2 cables are missing, I need to “lod” them on to the 2 coils?

Ok i see now what you meen. you have a diverent 4 coil icnition than i have. I have the one whit 6 cabels
Do jou have brake lichts on your bike?
I think the plastic plug is powerd by 3 coils, and powers multiple applications. So no need to “lod” the coils.

I can,t find a proper diagram on this site.

I have no bike for the motor at all 🙂 Just bought the motor.. I’m used to the 6 cable version, thought first this was a 2-coil ignition but got surprised when opened it and it was 4 coils inside..

I have looked for the schematics aswell, haven’t found any. will look closer tonight how all the oils are connected

Is this a piaggio or a Berini engine?

[sx3-sweTopic starterBerichten: 290]

I have no clue to be honest, the crank-case have many piaggio logos on it.
Also the flywheel have piaggio logo and some “Patent, made in the USA” or something similar, I can check tonight.
Is there any other sign I should look at?

It might be possible that this engine is from a “baghee” the indian version bravo, made under piaggio license.. I’m not sure though!

EDIT – EDIT – EDIT – EDIT – EDIT –
Does it matter in which order the coils/spoels are? I have 1 spoel which is insulated and red, that is the green cable to the CDI. This spoel is right next to the pickup, all other pictures I have seen on the internet, this special spoel sits on other place on the stator, but have the same green to CDI, If I buy a C24 ciao, I will rebuild the spoel to 6 cables, will I need to change place of the special spoel to another placement?

Yes it does matter to which coils your cables are connected. The coils itself are different by volts.

The following list is of how i have connected my coloured cables to the staator or coils;

Red = Pickup
White = On the stator
Green = Coil with the white tape on it.

Brown = Coil 1
Yellow= Coil 2
Blue = Coil 3

Thanks,

I understand the difference in voltage.
But the position of the coils on the stator, that doesn’t matter right? As long as right cable is connected to the right coil? Because my taped coil have different position than other pictures of 4-coil stator.

my other 3 coils are connected in series together, then only a yellow cable.
The thickness of copper wire is the same on all 3 normal coils

Is it only the taped coil that differs in voltage? The other 3 coils gives the same voltage?

Here is a picture of my stator.

And this is different position taped coil:

[zevenenergieDonateurBerichten: 4167]

no the special coil is fine where it is. But if you want to change the position its ok to do so.
It doesn,t matter at all.

The 3 coil are the same becours thay feet one pont.
And yes the igniton(special) coil has a diferent votage

[MartinoModeratorBerichten: 7384]

Well although these coils look the same they don’t have the same output. Did you tried to connect your lights to the brown or yellow cables for instance? You will see the lights burn stronger with the one cable and the other cable the lights are more dim.

Hmm, my stator don’t have any brown, only 1 yellow, which is powered by 3 coils in series, the coils are not individual as they are on other stator, which have blue+brown.

I realize that the other stators have different thickness of copper wires on different coils, look at above picture.. Thinner wire will give more laps around the holder generating a higher voltage.. Mine are thick, all of them, I think thats why they are connected all 3 in series, to induce enough power run the lights, through the yellow cable.

Which means I won’t be able to rebuild the stator to a 6 cable version, because the 3 coils will induce same voltage, due to same thickness, and same amount of laps around the holder..

There is really no good reason to make six wires. You have to put the 3 wires of your moped to together and connect it to your engine. 😉

[sx3-sweTopic starterBerichten: 290]

But then I won’t have any low/high power on koplamp och brakelight I guess? Because everything is same voltage on the moped?

[zevenenergieDonateurBerichten: 4167]

Yes, thats the limitation off this ignition.:D
