By the way you're talking, the bike is equipped with a single fire ignition. Your use of the term "top winding" indicates that there is a "bottom winding" or two windings on the coil. A single fire coil will have three small connections on it. A dual fire coil will only have two primary connections. In the dual fire system, both spark plugs fire at the same time where they fire individually on the single fire. Please check the ignition system out further and tell me if it's a stock ignition system or some type of aftermarket system. Either way, no spark to the rear cylinder indicates a bad ignition unit.

Good Luck
Steve

I have a 2001 roadking police bike. it has no spark. the bike cranks fine the fuel pump works, I checked all fuesess relays. checked the ckp sensre for metal ,checked the pickup senser metal. checked




Are the plugs installed because without compression you will not get ignition/spark.

Are there any codes set???

Is the ignition fuse okay??? Is ECM fuse okay?

Of course first you need power to the coil which should be there whenever the ignition and run switches are on if so see below:


Are the plugs installed

Remove the coil. THEN set your ohmmeter scale to RX1 and place ohmmeter leads on the primary coil windings A (front of coil) to B (middle of coil), B to C (front of coil) and check for primary coil winding resistance which normal resistance range is 0.5-0.7 ohms. If primary resistance is not within this range check out test results below.


Ignition Coil Secondary Circuit Test

With the ignition coil removed from the motorcycle and the ohmmeter set to the RX1K scale place the ohmmeter leads on the secondary coil windings B (middle terminal) to

R (rear secondary terminal/socket), B to F (front secondary terminal/socket) and check for secondary coil winding resistance which normal resistance range will be 5.5-7.5K ohms. If secondary resistance is not within this range check out test results below.


Test Results

A low resistance value indicates a short in the coil winding which requires coil replacement.


A high resistance value might indicate that there is some corrosion/oxidation of the coil terminals requiring the coil terminals to be cleaned and the resistance test then repeated and if after the test is repeated the resistance is still high after the terminals were cleaned the coil must be replaced.

If there is an infinite ohms or no continuity) resistance value the coil is open and must be replaced.


If you have spark, it sounds like either the sensor in the timing cavity of the engine is bad or the electronic ignition unit is bad.

How do I check the ignition coil


Ignition Coil Primary Circuit Test

Remove the coil. THEN set your ohmmeter scale to RX1 and place ohmmeter leads on the primary coil windings A (front of coil) to B (middle of coil), B to C (front of coil) and check for primary coil winding resistance which normal resistance range is zero point five and zero point seven ohms. If primary resistance is not within this range check out test results below.


Ignition Coil Secondary Circuit Test

With the ignition coil removed from the motorcycle and the ohmmeter set to the RX1K scale place the ohmmeter leads on the secondary coil windings B (middle terminal) to

BIKE RAN GOOD BUT HAD BACK FIRE ONCE IN A WHILE REPLACED COIL RAN GOOD FOR 100 MILES SHUT IT OFF NOW HAVE NO SPARK TO PLUGS


Could be an ignition module. Check the coil first.

Check your pick-up sensor located inside the timing cover, behind the adjustor plate. If the filament is not intact you will have no spark.
A defective coil, cam position sensor, or stator will also cause a no spark condition.

First check for diagnostic trouble codes (DTCs). THEN check the condition of the battery and do a voltage test
and recharge the battery if it is below 12.60V. THEN check the condition and tightness of the battery connections
and perform either a conductance test or a load test and replace the battery if and as necessary. THEN remove the spark plug cable from one of the spark plugs and remove the plug and visually check the condition of the plug. THEN attach the HT cable to a SPARK TESTER and clip the tester to the cylinder head bolt and crank the engine over looking for spark and repeat the procedure on the other cylinder also. Be aware that the Engine will not spark with both spark plugs removed, so when checking for spark, use a SPARK TESTER with both plugs installed.

I have a 1999 FXDL I have pulled the plug and have no spark at the spark plug. Just replaced the battery, now I do not know how to diagnose which part I need. Any Ideas?


Is this a 1999 or as posted in the category a 2002 DYNA. Depending on year you may have no spark with the plugs out but I think you are out of that vintage range. When did this problem start? What else has happened between no problem and present problem? First thing that needs to be confirmed is the spark situation.


Depending on the year of your bike the following may apply:

Ignition Coil Primary Circuit Test

Remove the coil. THEN set your ohmmeter scale to RX1 and place ohmmeter leads on the primary coil windings A (front of coil) to B (middle of coil), B to C (front of coil) and check for primary coil winding resistance which normal resistance range is 0.5-0.7 ohms. If primary resistance is not within this range check out test results below.

R (rear secondary terminal/socket), B to F (front secondary terminal/socket) and check for secondary coil winding resistance which normal resistance range will be 5.5-7.5K ohms. If secondary resistance is not within this range check out test results below.


Test Results

A low resistance value indicates a short in the coil winding which requires coil replacement.


A high resistance value might indicate that there is some corrosion/oxidation of the coil terminals requiring the coil terminals to be cleaned and the resistance test then repeated and if after the test is repeated the resistance is still high after the terminals were cleaned the coil must be replaced.

If there is an infinite ohms or no continuity) resistance value the coil is open and must be replaced.


If you have spark, it sounds like either the sensor in the timing cavity of the engine is bad or the electronic ignition unit is bad.

Fxdb street bob will not start


Start off with what year is it. Then do you have spark and fuel and compression? Possibly bad gas or you got diesel instead of gas or ??????????

Do you have spark?? Could be the ignition module also.

A lot of guessing with no model year. I would not be afraid to start off with a set of new plugs either.

2006 dodge caravan, 6 cyl. relaced cole, sparkepugs and wires in oct. 2009. Engine is reading #2 cyl. misfire again. Why


Firts time swap spark plug & ignition coil between two different cylinders and read again if the same #2 cyl. misfires !
If #2 cyl. is OK and another cyl. misfires then spark plug or ignition coil is out of order and must be replaced.
If #2 cyl. misfires again then #2 injector must be checked !
If ignition coils & spark plugs (complete set for 6 cyl.) are replaced then you must check #2 injector !

How can you test the spark plug coils, what is the resistance specs on spark plugs ignition coil for a jaguar 2000 s type V6. 3.0L


Dear Pablo,
You can check the input voltage at each coil. This way you make sure you have the proper amount to operate. Disconnect the six ignition coil connections. Turn the ignition key on. Check the voltage at Cyl #1 B/Y wire, Cyl#2 B/U wire,Cyl #3 B/O, Cyl#4 B/G, Cyl#5 B/R, Cyl#6 B/W and ground. It should be 10.5V or higher. If not,you need to find the cause of the voltage drop.
If ok, you can test the resistance of each coil. At the coil,measure the resistance across the primary windings.It should measure between 0.50 Ohms ans 1.00 Ohms.
I hope this information is helpful.If you need anything else,don't hesitate to ask. Thanks,Chuck.

Need a ignition coil an can't find one its all i need for it to run well an i dont know what to do... can i just ****** rig a car coil an what not an if so how an with what?


the secondary winding ( ignition coil) for that bike is pretty generic and can be found easily for 20 -30 dollars. I DO NOT recommend rigging anything on a motorcycle.
Sources might include your local bike shop, a parts/ salvage yard, dennis kirk.com , e-bay, craigslist , etc.

The rear cyclender stop's firing when bike is hot


You have a bad rear coil, or if the bike has a signle coil the rear cyl section of it is bad.
