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.
