How do you test a 1995 Kawasaki jet ski ignition coil?

To test a 1995 Kawasaki jet ski ignition coil, first, disconnect the coil from the spark plug and the electrical connections. Use a multimeter to measure the primary resistance by connecting the probes to the two terminals of the coil; it should typically read between 0.5 to 2 ohms. Then, measure the secondary resistance by connecting one probe to the terminal and the other to the high-tension output; this reading should generally fall between 5,000 to 15,000 ohms. If the readings are outside these ranges, the coil may be faulty and should be replaced.
