- If your dirt bike has been running recently, allow it to cool down completely to avoid any potential burns.
Locating the dirt bike coil
The next step is to locate the dirt bike coil. The coil is typically found near the engine, connected to the spark plug wire. Refer to your dirt bike’s owner manual or follow these general guidelines:
- Identify the ignition system of your dirt bike.
- Trace the spark plug wire from the spark plug to the source.
- Look for a component resembling a small cylinder or box connected to the spark plug wire.
Disconnecting the dirt bike coil
Once you have located the coil, it’s important to disconnect it from the ignition system before testing. Follow these steps:
- Identify the wire harness or plugs that connect the coil to the ignition system.
- Use your hand or an appropriate tool to carefully disconnect the wire harness or plugs.
Setting up the multimeter for testing
Now it’s time to set up the multimeter for testing. This will help measure the resistance of the coil. Follow these guidelines:
- Ensure the multimeter is set to the resistance or ohms (Ω) function.
- Connect the test leads to the proper ports, following the manufacturer’s instructions.
Measuring the resistance of the coil
With the multimeter properly set up, you can now measure the resistance of the coil. Follow these steps:
- Connect one test lead of the multimeter to the primary terminal of the coil.
- Connect the other test lead to the secondary terminal of the coil.
Interpreting the test results
After taking the resistance measurement, interpreting the test results is essential to determine whether the coil is functioning properly. Here’s what to look for:
| Resistance Value | Interpretation |
|---|---|
| Within the specified range | The coil is functioning correctly. |
| No reading or infinite resistance | The coil is faulty and needs to be replaced. |
Testing the primary and secondary windings separately
In some cases, it may be necessary to test the primary and secondary windings of the coil individually. Follow these steps:
Testing the Primary Winding:
- Disconnect the test leads from the secondary terminal.
- Connect one test lead to the positive terminal of the multimeter.
- Connect the other test lead to the primary terminal of the coil.
- Check the resistance value displayed on the multimeter.
Testing the Secondary Winding:
- Disconnect the test leads from the primary terminal.
- Connect one test lead to the positive terminal of the multimeter.
- Connect the other test lead to the secondary terminal of the coil.
- Check the resistance value displayed on the multimeter.
Replacing the coil if necessary
If the coil fails any of the resistance tests or shows indications of a fault, it’s time to replace it. Ensure you follow the manufacturer’s instructions or seek professional assistance in selecting and installing a new coil. Remember, a properly functioning coil is crucial for optimal dirt bike performance.

Additional Tips For Maintaining A Dirt Bike Coil
Regular inspection and cleaning
Dirt bikes are exposed to various elements, including dirt, mud, and water, which can affect the performance of the coil. Regular inspection and cleaning are essential to ensure the coil remains in optimal condition. Start by visually inspecting the coil for any signs of dirt or debris buildup. If you notice any, gently remove the dirt using a soft brush or cloth. Avoid using any harsh chemicals or abrasive materials that may damage the coil.
To further clean the coil, you can use compressed air to blow away any remaining dirt or debris. Be sure to hold the nozzle a few inches away to prevent any damage. Additionally, check the wire connections for any loose or corroded terminals. Tighten or clean them as necessary to ensure proper electrical contact.
Protecting the coil from damage
The coil of a dirt bike is vulnerable to damage from various sources, including rocks, branches, and crashes. To protect the coil from such potential harm, consider installing a coil guard. A coil guard acts as a barrier, shielding the coil from impacts and preventing direct contact with any external objects. Make sure the guard you choose is compatible with your bike’s make and model and securely mount it to the bike frame.
Another way to protect the coil is by ensuring it is properly secured to the bike. Check the mounting brackets and hardware regularly to confirm they are in good condition. Replace any worn-out or damaged parts and tighten all bolts to prevent the coil from shifting during rides.
Other preventive measures for prolonging the coil’s lifespan
Aside from inspection, cleaning, and protection, there are other preventive measures you can take to extend the lifespan of your dirt bike coil. These measures include:
- Optimizing the bike’s suspension to reduce excessive vibration, which can strain the coil.
- Regularly inspecting the spark plug and ignition system to ensure they are functioning properly, as any issues in these areas can contribute to coil problems.
