What are the Kawasaki ignition coil problems? How to fix the issues? As the Kawasaki ignition coil is a significant part of the engine, you have to be careful about it.
A bad ignition coil cannot supply enough power and voltage to the engine, reducing the power of the lawnmower or other vehicle. Replacing the Kawasaki ignition coil is the primary solution to most of the problems.
In this article, you will get to know the problems of the Kawasaki ignition coil and their corresponding solutions. Let’s go through this page and find the answers to ignition coil problems.
Kawasaki Ignition Coil Problems and Solutions
At first, have a glance on the problems you might face due to a bad ignition coil in Kawasaki engines.
When the Kawasaki ignition coil has issues, it affects the performance of your car. That is why you should be careful about the bad ignition coil symptoms of lawnmowers. According to the faulty, solve the issues as soon as you can.
The solution to Kawasaki Ignition Coil for Engine Starting Issue
Difficulty in starting the engine is a symptom of the problem with the Kawasaki ignition coil. This issue is caused by the spark plug of the ignition coil.
- First, inspect the spark plug of the ignition coil. It can be cracked or damaged badly.
- Then, you have to replace the spark plug to have the previous performance of the engine.
- The solution to Engine Misfire
When the ignition coil is faulty, it can make the lawnmower stall. An irregular spark occurs, and it causes the engine to misfire.
You will understand this engine misfires when you hear a noise like sputtering or coughing within a strong vibration. A foul smell of gas also occurs for the ignition coil failure Kawasaki.
The solution is to replace the ignition coil.
Solution Poor Fuel Economy
When a lawnmower ignition coil is damaged or problematic, it cannot serve enough power to the spark plugs. Then the engine starts to use more fuel, and then the lawnmower gets less run power than usual.
When you find this issue, you have to run the Kawasaki ignition coil test and then ensure that the problem is with the ignition coil. If you are sure of the ignition coil issues, you have to replace it as soon as possible.
The solution to the Engine Light Issue
The check engine light is a great source to find the problems with the ignition coil. Actually, it is designed with the feature to tell the issues. There are other problems with the engine which causes the light to keep on. You can understand the type of the issue by the codes. The engine codes P0300 to P0312 show the engine misfire problem, while the P0350 to P0362 show the problem with the ignition coil.
When the problem is with the ignition coil, you have to run the necessary tests and then replace it.
Replace the Kawasaki Ignition Coil-The Major Solution
Step-1: Safety Measures
As there are some risks for the hot engine, you have to take proper safety first.
- Apply the emergency brake of the lawnmower.
- Open the hood of the mower
- Let the engine cool down completely
- Disconnect the battery cable for the negative connection, if the manual says.
Step-2: Remove Ignition Coil
Removing the ignition coil is quite a tough job because of the lack of accessibility of different engine parts. Moreover, different regions tend to stick together. When you try to remove one from the other, it can tear apart. So, it is wise to follow the instructions from the manual to remove the ignition coil from the engine. Follow the general steps for the removal of the ignition coil.
- Locate the ignition coil first. Next, disconnect the electrical plastic pigtail connector. Be careful while handling the connector.
- Then open the screws that connect the coil to the engine. Now remove the coil carefully with gentle handling.
- To remove the spark plug, you have to twist the insulator boot slide. It is easy to break, and you have to be careful. If some portions of it get stuck, use the needle-nose pliers to remove it carefully.
- If the engine has more than one ignition coil, remove them one by one. Do not rush to remove all of them at once.
- After removing the coil and the spark plug, check the spark plug inner part and, on the boot, if there is oil or anti-freeze contamination. If you see any contamination or leak, repair it.
Step-3: How to Test Small Engine Ignition Coil with Multimeter
To identify the coil failure, you have to read the code. As the code only determines many reasons that can cause the misfire and the misfire, you cannot be sure of the bad ignition coil status. To test the ignition coils, follow the steps below.
- As a first testing process, swap the suspect coil with the other coil. If there is still a misfire to the suspect coil for the other cylinder, then the failure of the coil is sure.
- As a second way to test the ignition coil, you can use a multimeter to determine if the primary and the secondary winding are faulty. When the multimeter reading is higher than the normal range, then you have to replace the coil.
Step-4: Lubricate the Coil and Re-install
If the ignition coil is not faulty and the fault is with other parts of the engine or the spark plug, you have to change those parts. Then you can re-install the ignition coil. Before installing it, lubricating the coil will provide a chance for them to work well. Moreover, if the coil is faulty, then replace it and install a new one. You have to lubricate the new one too before installing it.
- First, apply the dielectric grease to the inside of the ignition coil insulator boot. It will seal the coil to keep it safe from moisture.
- Now gently handle the coil and install it by pushing the coil on the spark plug.
- Then install the bolts that hold the coil.
- Now reconnect the electrical pigtail.
- Lastly, a small quantity of grease applied is recommended to the coil connector. Make sure that the connectors and the connector tab are locked and fit correctly.
Step-5: Finish the Installation
Install back the other remaining parts of the engine. Then connect the negative battery cable back. Now test the lawnmower to see if it is working correctly.
Checking the ignition coil after removing it and replacing it is the best solution for the bad ignition coil.
