15. IGNITION SYSTEM Pulsar CK 125 IGNITION COIL CONTINUITY TEST Remove the seat and fuel tank. (Refer to 4- 8.) Disconnect the ignition coil primary wire coupler and measure the resistance between the ignition coil primary wire terminals. Resistance: 0.20.3 Remove the spark plug cap and measure the secondary coil resistance between the spark plug wire and the primary coil terminal. Resistance: 3.24.8K 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: 4.25.2K Measure the resistance in the XK range of the electric tester. PERFORMANCE TEST CDI Tester Ignition Coil Test the performance with a CDI tester. · Operate the CDI tester by following the manufacturer`s instructions. · Use the special connector to connect the CDI unit. If the spark is weak, inspect the spark plug and CDI unit. If both of them are normal, replace the ignition coil with a new one. Spark Plug CDI Unit 15-3
