If the trigger is not working it will not fire.. the trigger is kinda like a set of points in an older engine...tells the ignition when to fire..

SOURCE: LOSE OF SPARK

Pull the plug back out of the cylinder and ground it against one of the head bolts, kick the engine over to see if you are getting a spark.

The only thing I can think of off hand is the flywheel key. Take the flywheel off and check the key. If it is broken, sometimes you cannot get a spark. Sometimes it will just backfire. Check it and I hope you are sucessful...Lee

SOURCE: Husaberg (FE 501-03)Stator problem

I have never heard of a stator preventing a motorcycle from starting. You need a professional, local, second opinion before you plunk down any bucks.

Unless that is, are you calling a magneto a stator? Does your motorcycle have a battery? If it has a battery, you probably do not have a magneto.

SOURCE: black max 7kw generator high voltage output

Those voltage readings MAY be normal.

The AC waveform may cause your meter to read inaccurately. You would need to use a TRUE RMS meter to accurately read the voltage.

The siple meters actually read the AVERAGE voltage and then are calibrated to mulltiply it by the "form factor" for a sine wave. OFTEN these generators don't produce a clean sine wave. A square-ish wave will read higher on the garden variety meters.

Compare the brightness of a lamp comparing to when run on your utility.

The frequency depends on engine speed ... yours is running a bit fast...check it under at least half load and if off, adjust the govenor slightly.

No spark to front plug have replaced coil already no fuel pump either

Check for power on the positive side of coil, if you don't check ignition fuse, if you do then check for a trigger signal on the negative side of coil while cranking, if you have a trigger signal then the coil is bad, if no trigger signal then you either have a bad ignition module and or a distributor stator that you just replaced or a wiring problem.

If there's a spark when the engine is cranked, it has ignition. The problem is either fuel or compression. ... Use your AutoTap Express DIY to look for an RPM signal from the Crankshaft Position sensor while cranking the engine. A bad Crankshaft Position sensor is a common cause of no starts.

I have no spark on my Yamaha virago XV 700. New coils, had stator check and its good. So what is wrong? Please help.

So you checked the stator (you mean pick up coil) that sends a signal back to the ignition module to trigger the spark by opening the circuit which causes the coil to induce a charge/spark. Are you sure they were properly checked and are in time. Is the gap ok? If you think all is ok now you should check your grounds (coils and ignition module if it is the grounded type). Check all wires to and from the ignition module. Do you have power to the ignition module, coils etc. If all this is ok then you will have to try a new ignition module. I hope this helps. Rod

Jerking outboard engine

Good Day Khairul,
Are the Carbs Synchronized To Open And Shut At The Same Time?
If This Is Correct ! Then Do You Need To Pump The Primer To Contine Running?
If Yes Then Replace Fuel Pump DiaPhram
It Coud Still Be An Electrical Fault,
Coil,Trigger Or Stator .
Check To See Condition Of Plugs After Running,
Hope This Helps

2000 Mercury 75 outboard 3 cylinder with 3 carburetors and 1 coil per cylinder. No spark. Need wiring diagram please.

No spark can be attributed to two components; The stator or the trigger assembly. Even if you had a diagram (available online @ Mercury), you will still need a test harness,a DVA adapter and a meter to measure the resistance of the CDM's (capacitor discharge module) ,stator and trigger assembly. Best case fix would be the trigger, most expensive would be the stator. If you remove the flywheel, and inspect the stator, you can inspect the the coils that are coated with a white epoxy, and if one or more are bad, they sometimes leak a black resin, indicating the coil(s) have been shorted and no longer provide voltage for spark.

Polaris 90 atv does not have spark the coil tested good

check the trigger coil inside the stator cover. sometimes these go bad and will not pick up a signal from the flywheel to send to the coil for spark. you can find complete stator assemblies quite cheap on ebaymotors.com that come with the trigger coil.

Chain saw will not start McCullough Mac Cat Super 16 AV 35cc tried replacing spark plug and run through start up by steps and still not starting and sounds as if not firing

I would check the stator which is located directly beneath the recoil its held on by two bolts usually it is attached very close to the crank or the fan . What happens is this can build up with rust especially if left outside and this can cause lost of spark. I would get a spark plug tester and see if you have spark. if not i would pull the recoil housing off and clean the rust of the stator. good luck

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!
