The voltage on the coils is present except at the instant of firing. The interruption of the voltage is what causes the coil to fire. The cdi box is what causes the voltage interruption.
The interruption is very hard to detect. You are not the first to be stymied by that box. If you have access to an oscilloscope, I think you can see the pulse if it occurs.

SOURCE: No spark

Check the side stand kill switch if your bike has one. 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 kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it. Check the fuses. How good is the battery? Try a jump start from your car battery. Is the handlebar kill switch on? Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Install new spark plug.

If that doesn't do it, 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. If still no spark, get CDI system and coils checked at the dealers shop. You can screw up a CDI unit checking it yourself.

SOURCE: Rapid popping/crackling noise in xr80

a four stroke will pop and backfire under decelleration when it is lean, or not enough fuel. (Jetting too small in the carburator) But, look at the spark plug for color, white is too lean, black is too rich, and chocolate is just right. Make sure the air filter is good and clean. And lastly... have the valves been adjusted?

2007 ATK dirt bike no spark


Hi, Ken and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
3. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Loose connection at ignition coil or plug between ignition sensor and CDI box.
5. Spark plug cables in bad condition, shorting / leaking, spark plug cable connections loose, check for spark leakage in the dark.
6. Faulty ignition coil, pick up coil, trigger coil or CDI box testing needs to be checked with an ohmmeter at 70 degrees Fahrenheit
7. Faulty safety switches clutch, kickstand, neutral, off/on etc.
8. Faulty ignition switch.

Hi there I'm stuck I don't know how to check the


Sorry but they either work or they dont.
If yours isn't working, replace it.
But before you replce it consider checking the other components, because ign mods are exspensive.
it sounds like you've been already checking the other stuff. heres what i'd check if your bike came to my shop.
1. battery fully charged, and can take a load. (weak batteries = weak ign power)
i have a bike that won't fire at all with weak battery. Make sure battery is good.
2. check for spark at plugs, make sure plugs are good. Pull plugs and turn motor over.
rest plug next to head and turn over, do not touch the plug while turning over
or you can be shocked.look for spark.
if you have spark , then you ign mod is working.
if no spark, then check #3
3. power to coils. check the power going into coils,
if power but no spark, then coil is bad.
if no power. check #4
4. power to coils comes from a ignition system ( points/ cdi /ign. module)
there is a stator and a rotor. and a signal generator. on your motor
the signal generator wire sends a signal to the cdi, every time the rotor rotates.
the ignition system (ign.mod) sends power to coil.
so if no signal to the cdi, then signal generator is bad
if signal going into cdi but not sending the power to the coils then the cdi/ ign. mod is bad.

Hope that helps
Best Regards

No spark at spark plugs and coil has tested good, there is sufficient current at pick up off the cam as well, bike ridden through hard rain and started acting up during ride and eventually shut down 10...


Sounds like the water got in somewhere crucial and is preventing the components from telling the coil to spark.

Don't laugh now, but try hitting any suspect areas with WD-40. I recently learned the WD stands for water displacing. It was initially invented as something that could remove water. But it is flammable so exercise caution.

This is surely frustrating and thankfully it doesn't happen often to Harleys. I sure hope you find the source and get it sealed.

I rode with a group of 15 bikes from south WI to the eagle rehab place up in Minnesota. It rained on us for almost 90 minutes but not one bike quit running. So, when things are sealed as they should be, Harleys can run in the rain.

Hope you get this solved and get back on the road.

Hi, I have a 1998 cbr 600f3. There are 2 coils on this bike for 4 cylinders and two wires coming in and 2 coming out(spark plug wires going out). I can only get one side of both coils to fire so the bike...


Hi and welcome to FixYa,

On the 2 ignition coils:
  • two wires coming in - black/white carries/supplies IGN + 12 to both coils and the ignition control module. Coil1 (left) is connected to the ICM by the yellow/blue wire while coil2 (right) is connected through the blue/yellow wire;
  • 2 coming out - left coil powers 1 & 4 while right coil powers 2 & 3;
  • 1 &4 will fire together; so with 2 &3.

Good luck and thank you for asking FixYa.

Hello pbck98:

>>The Following is a Basic Instruction File I Made for Checking the Coil/Ign Coil/Magnetron/Armature on Small Engines. Any Input is Appreciated.
>>**To Check the Ign Coil; Remove the Spark Plug/s.
>>With a Good Plug, Wrap a Wire Around the Threads of the Plug and Attach the Other End of the Wire to the Engine Block. >>Remove the Blower Housing (metal engine cover). The Wire that is Connected to the Coil/Ign Module from the Shut Off Switch needs to be Removed (unplugged) from the Coil/Ign Module.
>>Now Check for Spark at the Plug.
>>If Spark, then the Shut Off Switch or the Wire is Bad.
>>If Still No Spark, then the Coil/Ign Module is Bad. If there are Safety Switches on this Unit and the Coil is Good; you Need to Check the Safety Switches for Being Bad and Check the Oil Guard Switch also.**
>>If you have a New Coil/Ign Coil and Still No Spark, then
>>Turn the Coil Over and Check for Spark. Ign Coils are Wound 1 Way for Clockwise Engine and the Oposite Way for Counter Clockwise Rotation Engines. I have Seen Ign Coil Boxed Wrong and Turning the Ign Coil Over will Correct the Problem.
>>The Coil is Gapped to .015in from the Flywheel.
For Better Assistance;
>>Send me the Make, Model and Type or Spec Numbers Off the Engine, Please. With these I can Locate the Proper Manual and Better Assist you.
Please, Do Not Hesitate, If I Missed Something or you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance.
Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Be Happy. Thanks.

Good Luck
