How to Check Coil on Small Engine
When it comes to maintaining a small engine, one of the crucial components that require regular attention is the coil. The coil, also known as the ignition coil, is responsible for generating the high voltage necessary to spark the fuel-air mixture in the engine. Over time, the coil can become faulty, leading to engine performance issues. In this article, we will guide you through the process of checking the coil on a small engine to ensure it is functioning correctly.
Identifying the Ignition Coil
The first step in checking the coil is to locate it on your small engine. The ignition coil is typically located near the engine’s flywheel or crankshaft, and it may be attached to the engine block or mounted on the frame. Look for a cylindrical-shaped component with two or three wires connected to it. This is the ignition coil.
Checking the Wiring Connections
Once you have identified the ignition coil, it is essential to check the wiring connections. Inspect the wires for any signs of damage, such as fraying or bare wire strands. Also, make sure the connectors are securely fastened and not loose. A loose connection can cause the coil to malfunction.
Testing the Resistance
To test the resistance of the ignition coil, you will need a multimeter. Set your multimeter to the ohms (Ω) setting. Connect the multimeter probes to the coil’s terminals according to the manufacturer’s specifications. A healthy coil should have a resistance within a specific range, which varies depending on the engine model. Consult your engine’s manual for the recommended resistance values.
Interpreting the Test Results
If the resistance readings are within the acceptable range, the coil is likely functioning correctly. However, if the readings are outside the specified range, it may indicate a faulty coil. In this case, you will need to replace the coil to restore proper engine performance.
Performing a Visual Inspection
In addition to testing the resistance, it is also essential to perform a visual inspection of the coil. Look for any signs of damage, such as cracks or corrosion. These issues can cause the coil to malfunction and should be addressed promptly.
Conclusion
Checking the coil on a small engine is an essential part of maintaining its performance. By following the steps outlined in this article, you can ensure that your engine’s coil is in good working condition. Remember to consult your engine’s manual for specific instructions and recommended resistance values. Regular maintenance not only prolongs the life of your engine but also helps prevent costly repairs in the future.
