  • Buggy Depot Hi Marsharo, The charging and ignition systems are separate, although I have seen some cases of a bad rectifier inexplicably preventing spark. To eliminate this as a possibility, disconnect the rectifier. Weak trigger has been shown to cause a heat buildup inside of the CDI. Usually leaves a pea-sized bump mark in the back of the CDI casing where the internal capacitor is located. August 13, Marsharo Thanks for the reply. I have tried multiple wires in the bundle but no luck. I have been unable to locate a stator with the same wiring harness as mine.

    I have attached a picture. Which wires are left over? If you could upload pictures of your progress that would help. Try contacting the seller of your engine to see which type of stator came with that engine, hopefully they will be able to tell you. The ignition system should all plug in for your scooter without having to modify anything. Plug in the stator, CDI, ignition coil, solenoid, and starter switch and you should be able to start the engine. I have a Subaru Robins engine that runs great and I got the same output when I tested it.

    So assumed this is at least enough to get spark, if not run lights.. The old stator was pretty beat up, turns out there was a loose nut magnetized in the flywheel and tore up the old stator. The new one is a 6 pole setup just like the previous. Too small? Obviously the 6 pole worked originally before I bought it but then was damaged before I got it. I have nothing hooked up besides the CDI and coil. I then checked the CDI to ignition coil positive and get nothing at all.

    Same both. Pulling my hair out.

    Reinsert the plug back into the coil wire. Hold the electrodes of the spark plug close to the engine to ground it, and try starting the engine. If you see spark coming from the end of the spark plug, your ATV engine is getting spark. Keep in mind, on some models you will need to have the handle bar switch in the run position and the rear brake applied.

    Look for any other red buttons or kill switches that might have been pressed. A lot of quads have fail safes you need to think about when trying to start the engine. If you have a hard time being able to tell if you can see a spark or not, you could always have a buddy hold the electrodes of the spark plug.

    If he yells when you try to start the engine, you have spark. The electrical systems on these quads can get a little tricky sometimes. The most common reason an ATV is getting no spark is a bad spark plug, either the wrong plug all together or just not gapped correctly. Lets go over how to check these one by one.

    This is the wire that hooks up to the spark plug when it is bolted into the engine. Sometimes these wear out because the wire itself is usually exposed to dirt, rocks, and debris while riding. If the spark plug wire looks good, the next step is to check for bad connections or bad switches. To do this, disconnect the main electrical connector coming out of the engine.

    Doing this will unhook the kill switch, ignition switch, and all the wiring associated with those switches. Check to see if you get spark now. If you got spark after unhooking the main electrical connector, then your problem is one of those switches or the wiring for one of those switches. Now your task is to go through and disconnect each switch one at a time to find the problem part.

    It will help to have an ohm meter to check each switch and each wire separately. You will also need basic tools to get the ignition coil on and off the machine. If you want to be extra safe, you could unplug the battery before starting. To locate the ignition coil, simply follow the wire connecting to your spark plug. Once you have the ignition coil out, you can hook your multi-meter up to it to begin testing. Start by testing the primary side of the ignition coil, where the ignition coil was wired, not the side that goes to the spark plug.

    You should see between 0. That is a wide range because it varies from machine to machine. Next lets test the secondary side of the ignition coil. This is the side with the spark plug caps. If your ignition coil has two spark plug caps, simply put the red test lead in one and the black in the other. Look for around 16k ohms resistance, but again you should check your service manual for your specific measurements.

    If you only have one spark plug cap, you will take one multi-meter lead and connect to the spark plug cap and the other to the primary side power connector.

    You either have a single phase or a three phase stator. Three phase is the most common, and probably the type you have. To make sure, check the wiring harness coming from your stator, If you see group of three wires of the same color usually white, yellow, or black you have a three phase stator. A single phase stator will not have that set of three wires. To start with the three phase stator, set your multi-meter up for ohms.

    Now get the connector with those three same colored wires we talked about before. You are going to be testing each of those wires against each other.

    So leg one vs leg two, leg two vs leg three, and leg three vs leg one. You can do this by simply inserting the multi-meter leads into the connector. You should typically see between 0. But check your service manual for your specs on your machine. If your meter reads OL, that stands for open line, and you will need a new stator. To check if your stator is shorting to ground, simply hook one lead to a stator leg through the connector and the other to the stator body or chassis ground on your machine.

    You should not get any reading on your meter. If you do get a reading on any of the legs, you will need to replace your stator. I find it easier to remove the stator to do the actual testing, but that can be a pain all on its own. Hopefully you find your issue with out too much trouble. Electrical problems can be some of the most time consuming.

    Apply dielectric grease to prevent future corrosion issues. Plug the connector in and out a couple of times to establish a proper connection. Now test if this has fixed your no-spark issue. Check for damaged wires in the wiring harness If a wire gets damaged, exposing the metal leads, you may get a short to ground. Trace all the wires connecting the various components of the ignition system.

    If you find a damaged wire, repair or replace it. You can test the switch by performing a continuity test using a multimeter, a test light, or a simple continuity tester. Insert one probe into each of the two cables going into the switch.

    There should be no continuity when the switch is off and continuity when it is on. Turn the ignition key one step clockwise to turn on the power.

    Please do not turn it far enough to activate the starter. If the instrument panel lights up, you know you have power. Then turn off the kill switch. You should now see no light or any other signs of power. You now know that the switch works. Look for a small black box with five wires going to it.

    Locate the center wire, usually white with a black stripe. Use a tiny screwdriver to release the tap that holds this pin in the connector.

    Remove the black and white wire from the connector. When removing this wire, you disable all of the many safety switches commonly found on shepherd Chinese youth ATVs.

    With the center wire pin removed, reinstall and test if you get a spark by removing the spark plug and look for a blue spark. Do not attempt starting the bike as you will not be able to stop the engine with the white and black center wire removed.

    If you get a spark, you know that the issue is with a safety switch. Check the ignition coil The ignition coil generates the electrical pulses of current sent to the spark plug to create a spark.

    On single-cylinder ATVs, the coil is generally cylindrically shaped with two connectors at one end the primary side and one single high gauge ignition coil lead going out the other end secondary side. On ATVs with more than one cylinder, the ignition coil pack may have a more boxed shape, but it could be cylindrical as well. How to test the ignition coil using a multimeter With a multimeter, you can read the ohms resistance of the primary side and the secondary side of the ignition coil.

    Each of these readings can tell you whether the coil is ok or not. Locate the ignition coil. You will find the ignition coil by tracing back the spark plug wire from the spark plug end. Disconnect the ignition coil and remove it from the ATV. This makes testing easier and safer. Test the primary side: Put the multimeter to its ohms resistance setting. Place the leads on the leads on the primary side terminals of the ignition coil.

    Read the ohms resistance. Refer to your ATV service manual for the exact value for your bike. If you get a reading outside this range, the ignition coil is likely bad and needs replacing.
