Why is my quad not getting spark?

Why An ATV Has No Spark There are a few reasons an ATV won’t be getting spark from the spark plugs. 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. Or the spark plug just went bad, that happens quite often and it’s normal.

How do I troubleshoot my ATV no spark?

1. Confirm that the ATV actually has no spark.
2. Make sure the kill switch is on.
3. Make sure the battery is charged and has good ground.
4. Check the spark plug.
5. Check for loose, damaged, or corroded connectors.
6. Check for damaged wires in the wiring harness.
7. Check the kill switch and other safety switches.
8. Check the ignition coil.

How do I troubleshoot no spark?

If you do not see a spark, there is an ignition problem. Remove a plug wire and insert an old spark plug or a spark plug tester into the end of the wire (the plug boot). Place the spark plug on a metal surface on the engine, or ground the spark plug tester to the engine. Then crank the engine to check for a spark.

What if my ignition coil has power but no spark?

If the ignition coil does not have spark, it’s time to check its wires. Use a test light to check the continuity on the signal wire and power wire on the ignition coil. If both wires are functional but the coil fails to produce spark, the ignition coil or the ignition control module is bad.

Will a bad stator cause no spark?

Without a stator, your motorcycle will not get any spark at all as your battery is not capable of supplying the appropriate power levels to generate a spark. As a result, if your stator is going bad your motorcycle will run very poorly. Eventually, your stator can prevent your motorcycle from starting at all.

What are the symptoms of a bad CDI box?

Symptoms could include misfiring, dead cylinders, backfiring, bizarre tach behavior, and countless other things related to how your engine’s running. The problem may get worse as the bike warms up. It might not even hold low revs at all.

What would cause no spark from coil?

Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.

What would cause a coil not to fire?

There are a few reasons for no spark, new coil pack could be defective, crank sensor, ignition module or bad wire in primary circuit, faulty ECM/PCM. You may have to have a good technician have a look, diagnose and estimate repair.

Can ignition switch cause no spark?

No spark is one of the most common causes of a no-start condition. It’s the first thing I check for. The igniter or ignition module, the pick up coil or crank sensor, the cam sensor, and the ignition switch are included.

What are the signs of a bad stator?

The most obvious symptoms of a bad motorcycle stator include no spark, weak spark, or intermittent spark (also known as misfiring). Hard starts and a poorly running engine can also be clues that your stator needs to be rebuilt or replaced.

Will ATV start with bad stator?

The stator of an ATV works to recharge your battery while your vehicle is running, similar in function to a car’s alternator. When the stator goes bad, your ATV will only run until the battery goes dead, which is not very long. Test the stator with a multi-meter to ensure that this is the problematic part.

How to test for no spark on an ATV?

CDI, Ignition Coil or Magneto Stator. Here is where you plug in your NEW SPARE CDI that you keep on hand for testing along with your new cheap spark plug. If we plug in a new CDI and still no spark, then we will plug in a new ignition coil and retest, still no spark, we finally will replace the stator magneto in the left side DRY engine cover.

Where is the spark plug on a Chinese ATV?

Number 2 is the ignition coil and that is easily found because the large wire and cap going to your spark plug is attached on the other end. Find your coil and make sure the small two wires are connected good and not pulled loose. The final third component is the stator magnetor or magnetic pickup coil.

How does a CDI test for no spark?

When these magnets spin around passing the ignition pickup coil mounted on the stator plate, the pick up senses the magnet and tells the cdi to tell the coil to fire that plug. Here is how we test this 5 PIN CDI system when arriving in our shop and our spark plug tests show that we have NO SPARK.
