17. IGNITION SYSTEM ATV 300/250 IGNITION COIL INSPECTION CONTINUITY TEST Remove the front fender. (Refer to the chapter 2) Remove the spark plug cap. (Refer to the chapter 6) Disconnect the ignition coil wires. This test is to inspect the continuity of ignition coil. Ignition Coil Measure the resistance between the ignition coil primary coil terminals. Resistance: 3.44.1 /20C Remove the spark plug cap and measure the secondary coil resistance between the spark plug wire and the primary coil terminal. Resistance: (with plug cap): 19.8 K/20C (without plug cap): 14.45 K/20C This test is for reference only. Accurate test should be performed with a CDI tester. Measure the spark plug cap resistance. Remove the spark plug cap and measure the spark plug resistance. Resistance: 4.25.2 K/20C Measure the resistance in the XK range of the electric tester. 17-6
