CDI IGNITION might have gone bad but i doubt it. check all your fuses and make sure they are good!! You have to get 12VDC to coil then you should get spark to sparkplug. Good luck and let me know how things turn out. HDTV GURU JAY

Hi Alan it's either the pick up coils on the motor or the cdi unit or wiring

1997 yamaha xj600 wont spark


Spark plugs. Or the coils. Just because there is power going to them doesn't mean they are working. But as they are fired by the CDI unit you might like to look there. Mine was a failed coil. If the problem is on both coils, it can only be the CDI.

Does cdi affect ignition in pulsar 150


yes the cdi is most importing.the starter coil supply electricity to cdi then cdi forward electricity to high tension coil,and high tension coil forward the electricity to spark plug,spark plug give more fire to piston.cdi not only supply only electricity,cdi adjust the electricity and control the power.ok?

I have a 2010 Oliver City CPI, motor scooter. The engine wont start. The starter seems to work and theres gas in it. Tried the kickstarter and wont start. bad spark plug maybe?


My problem started like this,I found No spark so changed coil,cdi,voltage reg,eventualy found stator at fault,check pick up strip on flywheel and pick up pin on black pick up coil,this is fixed to stator and sends spark signal to cdi,mine were both rusty/dirty,I fitted a new stator,but now have light problems..stator seems to be to strong.

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

My 1995 yamaha vmax motorcycle starts fine. when it warms up after a bit it shuts down. the shop is puzzled. they said that all 4 coils test out fine but when it is warm they all 4 just stop. no spark goes...


have them test the cdi box. it is your electronic controler for your ingnition timeing. it could be getting hot and shuting down. when it shuts down. the can take a wire from the negative side of the coil and ground it to the frame touching it and letting go of it instintly and if it sparks its not the coils it will be the cdi box or something to do with the electronic pickups in the motor that gives the signal to the cdi. that it is the correct time to trigger firing. hope this helps out.

No spark on 1998 Cagiva Canyon


did you check the primary coil? the ignition coil?if you think that these are all good,then you must replace the CDI.You cant test a CDI if this is good or not because it is a form of IC or integrated circuit,unless you have a manufacturer's diagram of it.You can check it by by detaching into its plug and get and replace an old CDI which you know is working,for example,get the CDI of the other motorcycle (if it has)the try to plug-in ,and if it fires,then thre you can surely know that the problem is on the CDI.

Kawasaki zx 6r, no ignition spark from plugs. Coils get 12 v. it seems that cdi is working as griund seems to be cut when trying to star. I have checked the plugs against motor and frame.


check your spark plugs leads
the CDI unit need to be tested for power and make sure that no wires are touching the frame as this could stop your ignition .
the cut off switch could be faulty too .
check all power sources around your motor as a wire could easely burned and earth itself .

No spark


There are a # of things that can take your spark out, first I would see if you have power to your ignition coil (100V+). If none there you need to isolate your ignition switch (unplug it or take it out of the equation) and jump your starter solenoid manually or try pushstarting the bike. If still nothing check for voltage going into your CDI box, if none check for voltage out of your stator (over 100V) and your trigger or pulse coil (over 3V). If you find voltage at the stator and not the trigger replace the trigger and vice versa. If there is voltage for both replace CDI box (but be cautious to verify good ground for CDI box and ignition coil). If you find voltage out of your CDI box (over 100V) replace your ignition coil. Good luck!
