SOURCE: ZXR250 CDI PROBLEM

Hi and welcome to FixYa,

If somehow, the CDI could be opened up, then component level repair maybe tried. There would be 2 final transistors that actually do the switching; 1 for each coil. Offhand, it would appear that 1 of those 2 is faulty. Otherwise, replacement is the only option.

Incidentally, in some versions, a fault in the tachometer could also cause one of the CDI's output to fail.

Postback results of tests.

Good luck and thank you for using FixYa.

Have fun, I don't know why it can't be as simple as just install the part and put it back together. You will have to swap wires around until you find the right combination.
Hope this helps.

Sounds simple, but do you have a kill switch on your scooter? Be sure it is not in the kill position.

A 2004 bear tracker and rebuilt carb. I used my lawnmower battery to crank the engine and while running, the CDI box began to smoke. with battery dissconnected,the CDI box continued to smoke. why?


Hi, Donald you may have fried your CDI box and it needs to be tested and or replaced for this situation I would call my local dealer or reputable shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry. If necessary, transport your bike to the dealer or shop and have a professional technician take it for a test drive, if it is in running condition, and give you a written estimate of repairs and answer any specific questions you may have about your issue. For more information about your issue please visit the website below. Good luck and have a nice day.

My 1980 pe 250 is getting fire from magnetio to cdi box but not to coil put new cdi box off a running pe 250 and still no fire to coil


Check the coil. Swap it with another if possible to check. Sometimes coils fail short-circuit on the primary. If so, you will see no signal from the CDI when attached to the coil.

I have a 1985 honda shadow vt500c, and like many others before me, im in need of a cdi box, or a fix to a broken cdi box, the used ones on line are a bit pricey for my wallet.


Unfortunately, the ONLY thing you can do is replace the cdi box....what REALLY sucks is that those cdi boxes were only used by Honda for 2 years...85 & 86...all the other years/bikes had MUCH cheaper units on them...And DO NOT, I repeat DO NOT waste your time on a USED part that is 30 years old!!! There is NO WAY to test a cdi box!!! Bite the bullet & buy a NEW one if you want to fix it & forget it.....there are new ones available online from a company in the UK for about $259.00 I speak from personal experience with this EXACT issue & once you replace the cdi box, that bike will run (providing everything else is good)

Best of luck!

Cdi box, I keep blowing them after installing i get about 5 minutes and then lose spark to 2 of the 3 coils on my 2005 Yamaha Vector. Help


I had the same problem with my 2006 Vector. Blown 4 CDI units. Changed out complete wiring harness and Stator, new plugs, Carbs. We narrowed it down to the coils. They were for an RX1 (based on the part number). swapped out with OEM vector coils. installed new CDI.. Sled is running flawless now.

Kawasaki 300 ATV has very faint to no spark until you stop trying to start, then a full second later, one big spark. Won't run. Any ideas?


Hi mate the cdi if failed you would have no spark period. I strongly recommend re checking stator when spark comes in and out or dies when hot or will only jump start these are all classic stator issues. simple test just need multimeter and read OHMS from the connecting plug of the stator... one of the pairs of wires will read sky high or zero... I don't know exact reading for your model but kwaka will tell you but a dodgy stator will generally read zero on one or more of the pairs of wires cheers mate hope it helps

Xt 500 has weak spark(flywheel magneto with ignition points).poor when cold and now won't even start.fuel fine.isolated ignition(magneto,coil and points).changed coil.points fine,resistance...


It sounds to me that you have done most all of what is needed. Just take some fine sandpaper to the magnets in the flywheel. After sanding, wipe it clean, then spray it with carb cleaner to remove any possible residue. Now give the magnets a spray coating of clear polyurethane coating. The flywheel will never rust again. Replace the source coil and install a new spark plug. A plug that is carboned up can lessen spark voltage. The last item is the battery. A weak one can rob power. Please rate my answer. Thanks.

I need help i have a 1990 yz 125 i have fire from the scatter plate to the cdi box i also have fire from cdi box what i need to know is how to hook it up to the kill switch and the coil


you run the positive lead from the cdi to the positive lead on the coil.... then somewhere between the negative lead on the coil and the frame/engine ground you splice in the kill switch.........what that does is breaks the ground when you push the kill switch which then kills the spark to the motor

No spark


Hi and welcome to FixYa,

To my understanding, the problem is 'no spark' yet the engine cranks. Generally, to consider are:
  • pulser coil (least likely);
  • ignition coil (likely);
  • interlocks (likely);
  • CDI (most likely).

Offhand, the CDI would be the main suspect. Since the CDI is sealed, it is not possible to do component level checks. The only way to check if the CDI is good is to check the external connections; if they are good and yet no spark, then the CDI is bad.

How to check the above:
  • to check the pulser coil, measure the low voltage coming from it using an analog/needle type AC voltmeter. While cranking, it should show a flickering low voltage;
  • to check the ignition coil, use a continuity tester. Primary should measure 3 ~ 5 ohms while primary to the high voltage end would measure 15 ~ 18 kilo ohms;
  • the ignition coil has 1 terminal connected to the IGN +12 while the other terminal is connected to the CDI. This should have a pulsating voltage when cranking.
  • all the interlocks could be checked with a continuity tester. Please note that most interlocks has a diode connected in series with their wires.
The interlocks include:
  • clutch switch;
  • side stand switch;
  • neutral light switch.

Good luck and thank you for using FixYa.
