Good possibility, You can check the out put voltage of the pickup coil. This has to be done with a "peak reading volt meter". There are some commercially available adaptors to insert in a standard volt meter for this check. With adapter installed, meter set to DC volts the reading across the leads from the pick up coil should be 3-7 volts at cranking speed. You should also confirm that you have battery voltage with the key & engine stop switch on at the cdi box as well as a good ground. I believe on a Suzuki this will be the orange/ white for battery voltage and the black will need to have contininity to ground. Also the orange/white at each coil should have battery voltage with key and engine stop switch on.

SOURCE: 1986 gsxr 400.not sparking r starting

rectifier/regulator is for changing the AC (actual current) from the alternator or generator to DC (direct current) for charging the battery and running lights etc... and therefor regulates power DC to 12volts this is to stop blowing fuses bulbs etc...

the cdi unit takes its power from the alternator/generator in the form of 2 pick ups 1 for each coil as the engine turns just like the old style points system just before top dead centre a spark is produced to each cylinder as it reaches TDC (top dead centre) therefor if a pick up in the alt/gen is dirty/faulty only 1 coil is recieving the spark via the cdi unit all components need to be checked
a good trial and error if machine sparks/runs on 1+3 cylinders only take the 2 wires that go to the coil 1+3 switch them with coil 4+2 if machine now sparks on 4+2 fault lies within pick up to that coil

SOURCE: my keeway wont start

Check the fuses. Is the kill switch on or shorting out? Disconnect it and then check for spark. Sidestand/centerstand should be up, Got a good battery?

I am unfamiliar with your Keeway and just trying to help. Don't give me a bad rating if I miss the mark on this one. Thanks.

Backfiring is typical for 'lean' conditions and stuck inlet valves.
check also the spark plug condition, replace them if any doubt on their age exists.
Check compression to discover open valves.
Clean out the carburettors.

Hey whats up? Try back probing your wires going to the CDI unit with a volt meter or continuity tester to make sure you do have any broken wires. Then check the stater make it is good. If sure how to check the starter take it a bike repair shop they should check it for free.. If that does work let me know and I will look further into it for you. Good Luck.

SOURCE: the engine turns over and everything but it wont start. no spark

I assume you got this fixed; sounds like it wasn't getting gas to the carbs. Some people don't realize the 99-02 SV650 has a vacuum-actuated fuel pump, and sometimes it can get stuck. Mine has had this problem, and it took me a while to determine it was the problem. I would guess it only happens after the bike has been sitting a while.

Best way to check it is to lift the tank (it's bolted to the frame on the right side of the engine just under the tank). Unplug the line toward the front of the motorcycle from the fuel pump, and connect some spare fuel hose to it running to a can next to the bike (don't want to get gas everywhere!). With everything else still connected, crank the bike for a short period to see if any fuel comes out (shouldn't take long). If not, then move backward and ensure fuel will flow from the vacuum-petcock when the bike is cranked. If that does work, your fuel pump needs some work. I was able to take mine apart and unstick it.

Hi, Anonymous the vast majority of service, parts, and owners manuals on the internet are "FREE" to download and all service manuals contain wiring diagrams in the back pages. The rest usually charge a modest fee around $10 and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available. Most of the manuals will cover your exact make, model, and year otherwise one will be provided that comes as close as possible to your bike and will have most of the same info that an exact manual would have.

1988 suzuki gsx 600 f getting power to coil but no spark good wires .what does cdi do to fire coils


The CDI grounds the coils, this causes the magnetic field to collapse and that generates the spark. Think of it as electronic points.

I have 1990 suzuki gsx 600f with no spark but does crank i have tried cdi box as i have 2 of the same bikes plugs seem fine checked all the wiring i don't know what it could be


Hi, Anonymous 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.

1988 Suzuki GSX 600 F no spark


Hi, Thortonroof and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead acid batteries.
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 module.
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 or electronic control module.
7. Faulty CKP, CMP, or BAS sensor.
8. Faulty ignition switch.
9. Tilt sensor needs a reset.
10. Security alarm failing to disarm needs reset

MY MATES SONS GSX 400 (94) HAS STOPPED WE CAN'T GET A SPARK. CHECKED THE PLUGS AND CHANGED THEM CHECKED THE IGNITION PICK UPS.. VOLTS GOING DOWN READ 6.8 COMING BACK UP READ 5.8.. NOT SURE IF THIS IS WRONG...


Just a thought, have you checked all the fuses are located correctly and connectors are all mating. CDI units do fail and there's no way of testing it at home, all you can do is check for supply voltage 12V, ground or negative bonding (using an ohm meter/multimeter) check for varying voltage from ignition pulse generator, finally check voltage at the coils, you should expect to see a fairly high voltage 11-12V. Not sure where you would get one as it's quite a rare bike, a Suzuki dealer would be your best bet, maybe a GSXR400 one will work but don't quote me on that.

Bike will not spark but gets gas


Check for 12v to coils & ignition box/ CDI/ unit. If good, Most likely CDI unit has failed. Try Ebay or salvage

Install new spark plugs and add a can of seafoam to your gas at the rate of one ounce per gallon to clean your carbeurator.

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!
