Fixing a Faulty Magneto: Troubleshooting and Repair Guide
Introduction
Dealing with a faulty magneto can be a frustrating experience, especially when it affects the performance of your machinery. In this guide, we will provide a step-by-step troubleshooting and repair process for fixing a faulty magneto. From testing the handle switch to inspecting the magneto, we will cover all the necessary steps to get your magneto up and running smoothly again.
Testing the Handle Switch and Kill Switch
The first step in diagnosing a faulty magneto is to test the handle switch and kill switch. By replacing these components and conducting a simple test, you can eliminate any potential issues related to these switches. Testing for continuity and ensuring proper functionality is crucial in this process.
Testing the Capacitor
Next, it's essential to test the capacitor. This cylindrical object located inside the magneto plays a significant role in its performance. By checking for continuity and ensuring it reads open, you can determine if the capacitor needs replacement or if it is working correctly.
Removing the Magneto and Inspecting
If the previous tests haven't solved the issue, it may be necessary to remove the magneto for a more thorough inspection. Removing the magneto allows for a closer look at its internal components and potential problems. Clean any accumulated dirt or debris, and examine the mating surfaces for any signs of damage or wear.
Removing the Muffler
Before proceeding with the magneto removal, it might be necessary to remove the muffler. If the muffler is damaged or in poor condition, this can affect the performance of the magneto. Repairing or replacing the muffler can improve the overall functioning of the magneto system.
Removing the Wheel to Access Magneto
In some cases, accessing the magneto requires removing the wheel. This step can be challenging, as the wheel is typically held in place by bolts that may have corroded over time. Applying a penetrating lubricant and using a broom handle and hammer can help loosen the bolts, making it easier to remove the wheel.
Troubleshooting Magneto Issues
Once the magneto is removed, it's time to troubleshoot the specific issues causing the malfunction. Various factors can contribute to a faulty magneto, such as worn-out cast fittings or internal damage. Careful inspection and bench testing can help identify and address these problems effectively.
Taking the Magneto Apart
Taking the magneto apart can provide a closer look at its internal components, allowing for a better understanding of potential issues. By dismantling the magneto and inspecting each part individually, you can identify any damages, misalignments, or electrical faults that may be causing the malfunction.
Fixing the Magneto Mechanical Issue
During the inspection, it's crucial to pay attention to the magneto's mechanical components. One common issue is dry rotting of the internal sealing components. Lubricating these parts with white lithium grease can help restore smooth movement and proper functioning.
Working on the Coil and Condenser
Another critical aspect of magneto repair is working on the coil and condenser. These components play a vital role in generating and delivering sparks for ignition. Cleaning the points, checking the gap, and lubricating the oil felt are crucial steps in ensuring their proper functionality.
Conclusion
Troubleshooting and repairing a faulty magneto can be a complex task. By following the steps outlined in this guide, you can effectively identify and address the issues affecting your magneto's performance. Remember to take the necessary precautions, seek professional assistance when needed, and enjoy the improved functionality of your machinery with a properly functioning magneto.
