Q
how to test a coil on a small engine
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
Testing a coil on a small engine, such as those found in lawn mowers or generators, is crucial for diagnosing ignition problems. Begin by ensuring the engine is off and cool. Disconnect the spark plug lead, and remove any covering to access the coil. Use a multimeter set to the ohms (Ω) scale to measure resistance. Attach one lead of the multimeter to the coil's ground and the other to the terminal. Different coils will have different resistance specifications, so consult your engine's manual for the correct values. Typically, a functional coil will show a low resistance (a few ohms) on the primary winding and a higher resistance (several thousand ohms) on the secondary winding. If the measurements are significantly out of range, it indicates a faulty coil that needs replacement. Always handle the components carefully to avoid damage and ensure accurate readings.
