How do you test a Mitsubishi montero sport ignition coil?

To test a Mitsubishi Montero Sport ignition coil, first, ensure the vehicle is turned off and disconnect the battery. Then, remove the ignition coil from the engine and use a multimeter to measure the resistance across the primary and secondary terminals. For the primary winding, a typical resistance should be around 0.5 to 2 ohms, while the secondary winding should read between 6,000 to 15,000 ohms. If the readings are outside these ranges, the ignition coil may be faulty and should be replaced.
