Hmm, something has been changed at some stage.
All wires should be of same colour combo's.

Best guess is three wires from cdi go directly to magneto, whilst the fourth is for the coil. However your configuration suggest a different cdi unit is being used, the site below has a diagram of your bikes standard electrics, unfortunately not color coded.

Normally, it cannot be wired incorrectly as male/female and color wires determine correct connections. Find out the origins of the parts and seek the application for the color of each wire, ie: color wire for primary source, pulse coil, earth, etc. Transfer this info to the colors from your magneto, Goodluck and cheers.

Hi Check that the kill switch is connected to the ignition & is working OK
There may be a carbon deposit on the head which is glowing red hot thereby igniting the fuel like a diesel (without a spark) The other possibility is dieseling by over compression (at 14:1 compression petrol self ignites) but that is not very likely

Hi, i have a denso cdi no. 32900-19b20 for atv suzuki quadrunner i dont know where each wire goes to. there are 5 wires orenge,black/white,green,black,white/blue please help me. t.y

this particular year was very unusual because it removed the multiple inputs from magnetos and just went with a single (2 wire) signal coil (green, black) which will ultimatly go into the left side case behind the pull start. the white/blue wire goes directly to the coil. the orange wire goes to the ignition and will have 12 volts when the ignition is powered on, then go to ground with ignition off. the black/white is constant ground. this year was different because the cdi let the regulator do all the converting from ac to dc. it is also one of the haardest years to find a box for used.

O3 rm 125 has no spark

check simple things first like, spark plug,try a new one or the plug cap,a bad earth frame connection in relation to the ignition system,cdi unit earth,ecu frame earth etc, etc 1. check the kill switch. 2.check the resistances in the high tension coil. Primary around 0.6 ohm, secondary around 15~20k ohms. 3 . check the output source coil , black/red~ red/white it should carry about 20~ 28 ohms with an output of around 30 volts. 4. last but not least check the pulse coil. red~ green 85~ 115 0hms.Glad to help Red.

19-95 KLF300 ATV Kawasaki 4x4 no spark put new ignitor unit on.

You said the motor cut out and popped and backfired when it quit, this is almost always one of two things; either the low speed pulse coil or the actual CDI "black" box. You will almost never lose a main coil. One thing I would also check to make sure did not happen is shearing a flywheel mag key. When the motor backfires you can easily shear a mag key if you have a heavy flywheel, (external). However when this happens you don't usually lose spark but it will certainly cause the backfire.
One other item of importance is that the bike you are in question about does not emit a bright spark when you are checking for fire. Make sure you are using a brand new plug and ground it on the head. Try to make sure you are in a dark environment when you check the spark.
