          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.
