Q
how to check 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.
To check a coil on a small engine, first ensure safety by disconnecting the spark plug wire. Use a multimeter set to the ohms (Ω) scale to measure resistance. Test between the coil's input (lead) and ground terminal; typically, a functional coil shows a low resistance value (a few ohms). Then, check the secondary resistance by placing one meter lead on the spark plug lead and the other on the coil's ground. This should read higher, often in the thousands of ohms. If measurements fall outside normal ranges, this indicates a faulty coil. It's also vital to inspect for physical damage or corrosion. A coil in good condition is crucial for reliable engine performance as it generates the spark needed for ignition. Always consult your engine's manual for the specific resistance values and testing procedures as these can vary.
