Before going to the CDI system go ahead and check the kill switches including the side stand switch, with an Ohmmeter. How good is the battery? Check the fuses. Check the wiring harness. Are all wires clean and with a solid connection? Any abraded wires? Check the operation of the ignition switch with a volt ohmmeter. Is the bike in neutral and the neutral light is lit up?

You can download a free PDF factory service manual by going to the website below >
http://www.carlsalter.com/motorcycle-manuals.asp
The manual should tell you in detail how to test the CDI and other electrics.

Please rate this solution. Thanks. > 4 diamonds would be nice!

Check the fuses. Next, check for spark but with a new spark plug. How good is the battery? If needed, add water to the battery cells enough to cover the top of the cell plates.Try a jump start from your car battery. Is the kill switch on? Check the operation of the ignition switch with a volt ohmmeter. You should be getting power into and out of the ignition switch.

If the bike doesn't start and run properly check the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. Broken or out of adjustment, it would kill the spark. Check for a broken wire at the switch or coupler. Get a service manual and check out the electrical section. Some bikes have a diode integrated into the turn signal relay. Try moving the kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it. If that doesn’t work, check out the relay.

Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires? Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center casing.

Please rate this answer. Thanks

  • Do you see spark? If not, check the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the side stand kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it.
  • Is the handlebar kill switch on? Is it shorted out?
  • Are you getting power to the coils?
  • Check the fuses. How good is the battery? Try a jump start from your car battery.
  • Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires? Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center or side casing. If still no spark, get CDI system and coils checked at the dealers shop.

Hi and welcome to FixYa,

Initially, test for the presence / absence of below described voltages using an analog / needle type voltmeter when starting the bike:

  • pulsating low AC voltage coming from the pickup coil;
  • pulsating voltage feeding the ignition coil.

Good luck and thank you for asking FixYa.

I have a 1987 rm 125 h need help on the wiring out of the magneto to the cdi box i dont have a plug on the mags wires the colors are black with a red stripe, green ,red , and re with white stripe the cdi...


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.

On my 92 rm 125 i put a new stater on it and where


Could be a bad coil, coil wire or module. The module converts the pulses of the stator so the coil knows when to spark. Bad coil = no spark. Bad coil wire = no spark to plug.

No spark put on a new cdi box coil good and a new stater


hi,sounds to me like your cdi pickup unit has failed,i am not 100% certain but this will be located on the end of the crankshaft behind one of the enginecovers,there could be two other possibilities,motox bikes are notorious for breaking wires so check the wiring from the cdi sender unit to the cdi box and the coil,also check your "off"button it may be stuck in the "kill" position..hope this helps..cheers ian

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.

Fresh rebuild now no spark


If it ran before, I would double check your electrical connections. Its more likely you didn't get a connector pushed all the way together or left off a ground wire. The ignition coil specs are generally 1 ohm or less on the primary (small Wire) side, and 5K-10K ohms on the secondary (spark plug) side. Each side should be tested to ground. Pick-up coils are typically open or really large ohm reading in Megaohms normally and around 100 ohms when the magnet on the flywheel passes by. there is no way to test the CDI box other than putting it on a know running bike or getting a known good CDI and putting it on your bike. Double check that the spark plug cap is secured to the high tension lead as well. Testing the stator is a little more complicated, but a quick way is to close the gap on an old spark plug to about 0.010" and see if there is a week spark. If so, the stator will need to be replaced.
