    hello mr fixit-jerr
    from paul

    i am not shure which ground wire (black) you proposed to check?
    the ignition coil is mounted on the plastic housing and is fired by the trigger
    coil mounted under the plastic engine cover on the out side of the fly wheel
    the trigger coil is set at 0.010. the the magnets are very strong. this is a wierd problem.
    maybe this will help the diagnostics?
    thanks paul

You engine has a low oil level sensor. If the oil level is low or..... the sensor is bad it will ground the ignition from the coil with the engine switch on. For troubleshooing only disconnect ONE wire from the sensor AFTER you make sure the engine oil level is properly serviced. Then check for spark.

If this does not correct the problem just respond and I will help you.

Thanks for choosing FixYa,

    Paul you have done all the correct things as far as parts replacements and measurements. All the readings you passed were good. Distances also. The only thing that can cause the problem now is a ground off the ignition unit black wire. Do what you have to to isolate that wire with the plug removed and test the spark. If you still don't have spark at that time I don't know what to tell you. I have been working on small engines for over 40 years. The biggest reasons for no spark are

    1. Grounds in the magneto / ignition unit areas

    2. Failed Ignition units

    3. Low oil pressure sensors and wires... the only time you should read a ground is with the ignition switch ON and the engine NOT running / no oil pressure. If there is a short before the low oil level sensor this can kill your ignition.

    4. Spark plugs

    5. High tension lead shorted where it passes through the cowling.

    Hi Paul,



    Another train of thought: Maybe we are looking in the wrong area all together. This unit has an overload shut down relay on it also. There just might be a problem with the overload relay and wiring. I don't have the schematic for this particular generator but...it sure would not be hard to figure out. I am just thinking after everything you have done it should have spark but... we totally forgot all about the overload trip relay. I think we should focus on that aspect in future troubleshooting.

    Paul... disregard my last post. I actually have the wiring diagram for this generator in pdf format. First off there is NOT a shut down relay on the diagram at all. I see the ignition sensor on the diagram... (your right seems to be a beast of a different breed) I am really not supposed to do this but if you pass an email address I can send you the diagram. I can not post mine here.

1998 gsxr 600 no spark


Instructions

Verifying the Spark
1

Remove the upper and side fairings, using a 4 mm Allen wrench to unscrew the fairing bolts. Unlock and remove the rider's seat, using the ignition key.
2

Pull the fuel lines off of the fuel valve under the left side of the fuel tank. Unscrew the pair of bolts from the base of the fuel tank, using a 10 mm socket. Pull the fuel tank to the rear of the motorcycle to remove it..

3

Pull the cables off of the two spark plugs on the right side of the motor. The spark plug cable furthest to the right is connected to the right ignition coil, while the second cable is connected to the left ignition coil. Unscrew the spark plugs from the motor, using a spark plug socket. Plug the ignition cables back onto the removed spark plugs.
4

Hold the spark plugs against the motor and start the motorcycle for a few seconds. Observe the gap between the electrode at the tip of both spark plugs for spark. Ideally, the spark should have a bright, blue appearance.
5

Replace the spark plugs with new DR8E spark plugs, if no spark is present. Repeat the test. Replace the corresponding ignition coil if there is still no spark present at the spark plugs' electrodes.
6

Proceed to Section 2 for further diagnosis, or reassemble the motorcycle following the reverse method of removal.
Testing the Windings
7

Remove the suspect ignition coil from the motorcycle's frame, using a 10 mm socket. Unplug the coil's cables from the remaining spark plug in the motor and from the spark plug removed in Section 1. Unplug the motorcycle's wiring harness connector from the back of the ignition coil. Remove the remaining ignition coil, if needed, using the same procedure.
8

Set your multimeter to read an R X 1 resistance range, using the meter's settings dial.
9

Measure the ignition coil's primary winding at the terminal that connects to the motorcycle's wiring harness, using your multimeter. Touch the meter's red probe to the coil's positive (+) terminal and the black probe to the coil's negative (-) terminal. Take note of the measurement on the meter's display. Replace the ignition coil if its primary winding has a resistance measurement less than 3 ohms or greater than 5 ohms.
10

Set your multimeter to read an R X 1,000 resistance range, using the meter's settings dial.
11

Measure the ignition coil's spark plug cables, using your multimeter. Touch the meter's probes to the metal connectors within the cable's end caps. Take note of the resistance measurement on the meter's display, indicated in ohms. Replace the ignition coil if the cables have a resistance measurement less than 25,000 ohms or greater than 45,000 ohms.
12

Reinstall the ignition coil if its primary winding and spark plug cables are within the specified resistance range, using the reverse method of removal. Replace the entire ignition coil if either the primary winding or the spark plug cables are within specification, as the ignition coil and its cables are a combined assembly.
13

Reassemble the motorcycle following the reverse method of removal. Connect the left ignition coil's cables to the pair of spark plugs in the middle of the motor's cylinder (#2 and #3), while the right coil's cable connect to the spark plugs on the sides of the cylinder (#1 and #4).

Generac 5793 Ix 2000 surging


It sounds as though there is an issue with the carburetor. If the unit is "surging" with no load I would recommend thoroughly cleaning the carb. It would also be a good idea to test the fuel pump. Per Generac you need to disconnect the fuel line leading to the carb and pull the starter rope over to see if adequate fuel is flowing. If none of this is the issue try testing the stepper motor on top of the carb. If you unclip the wire and use an OHM meter all wires should test at 150 ohms. to test place on test lead on the blue wire and move the other lead to the remaining four wires. The should all ohm out to roughly 150ohms. if this is not the case you need to replace the stepper motor.... Before you do any of this you should check for fresh fuel, a good spark plug, and proper compression.

1998 dodge stratus 2.5 s.ix cyl. no spark. only 4.09 volts coming from orange and green wires on distributor no voltage from feul injecter wires.


check the ignition coil or coil pack of their resistance,
primary must have 1.0 ohm to 0.5 ohms(tolerable).
secondary are between 900 ohms to 12,000 ohms

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.

My 1999 buick lesabre will not start. I have gasoline and the battery is good.


Hmm, do you have spark? fuel pressure must be between 30 - 40 psi test the ignition coils by connecting an ohmmeter between the coil towers ie 1and 4 with the key in the OFF position do the same with the others as well there are 3 coils all together...you should have readings between 5 an7 thousand ohms if so the secondary side of the coils are good, if there is no spark at all try an ignition module. this is under the 3 coils they sit on the ign module..You can also test and or replace the spark plug wires, if a wire is 10 inches long it should read 10,000 ohms or less.. No more than 1000 ohms per inch is the spec.. hope this helps good luck

If you have a volt/ohm meter, you may want to first ohm check the resistance between the two spark plug towers on each ignition coil pack. Simply remove the spark plug wires from each coil pack and test. Both (if good) should test about the same resistance, (about 5-7 kOhms, but I don't have the exact specs handy on this particular vehicle. The reading may be higher, maybe around 7-12kOhms) but nonetheless, the reading of the 1-4 coil pack should closely match the 2-3 coil pack. If not, the new coil pack may be faulty and should be returned for a replacement.

Also, when you remove the 1-4 coil pack, take a look at the primary spade connectors (2 lugs) coming out of the ignition module. Make certain these are clean and free of rust or corrosion. If so, simply (and gently) use a finger nail file or 400 (or equivilent) sandpaper to file the corrosion off and re-attach the coil pack.

If one or both of these don't fix the problem, you may have to look at replacing the ignition module. But only do that after exhausting the other simpler and less expensive tests! :)

I hope these tips help you out or at least point you in the right direction! :)

Fresh rebuild now no spark


If it ran before, I would double check your electrical connections. Its more likely you didn't get a connector pushed all the way together or left off a ground wire. The ignition coil specs are generally 1 ohm or less on the primary (small Wire) side, and 5K-10K ohms on the secondary (spark plug) side. Each side should be tested to ground. Pick-up coils are typically open or really large ohm reading in Megaohms normally and around 100 ohms when the magnet on the flywheel passes by. there is no way to test the CDI box other than putting it on a know running bike or getting a known good CDI and putting it on your bike. Double check that the spark plug cap is secured to the high tension lead as well. Testing the stator is a little more complicated, but a quick way is to close the gap on an old spark plug to about 0.010" and see if there is a week spark. If so, the stator will need to be replaced.
