Q
how to test a small engine ignition coil
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
Testing a small engine ignition coil is crucial for diagnosing engine problems. First, ensure safety by disconnecting the spark plug lead. Use a multimeter set to the ohms (Ω) scale. Measure resistance by placing one probe on the coil's body/metal casing and the other on the spark plug lead terminal; this tests the primary resistance. For the secondary resistance, place one probe on the spark plug lead and the other on the terminal where the ignition cable connects. The exact resistance values can vary, but generally, primary resistance should be around 0.4 to 2 ohms, and secondary resistance between 6,000 to 15,000 ohms. Values significantly outside this range indicate a faulty coil. It's a straightforward test, but consulting your engine's manual for specific resistance values is advisable for accurate diagnostics. Remember, a coil might pass these tests but still be faulty under load, so this method isn't infallible.
