14-5IGNITION SYSTEMIGNITION COILFIXING SCREWPULSE GENERATOR·Inspect with the spark plug assembled and whilethere is compression pressure.● Remove the CDI unit. ( 14-7 )● Remove the coupler from the CDI unit and connect thepeak voltage adaptor to the pulse generator wire (blue/yellow and green) of harness coupler.● Operate the starter motor and measure the peak voltageof the pulse generator coil.CONTACT POINTS : BLUE/YELLOW TERMINAL “⊕⊕”-BODY EARTH“⊖⊖”PEAK VOLTAGE : OVER 1.5V·When measuring voltage, do not touch the metal partof the handle rod as there is the danger of receivingan electric shock.● Perform the following inspections if measured peakvoltage in the CDI unit coupler portion is abnormal.● Disconnect the AC generator cord coupler and connectthe adaptor.● In the same manner as with the unit coupler side,measure peak voltage and compare with the first peakvoltage.● When the measured value in the unit side is abnormaland normal in the pulse generator side, the problem iseither incorrect coupler connection or disconnection ofthe wire harness.● When both measurements are abnormal, this indicatesa problem with the pulse generator. Refer to themalfunction diagnosis are go through each step.IGNITION COILREMOVAL/INSTALLATIONREMOVE● Luggage box. ( 3-3 )● Plug maintenance cover.● Spark plug cap.● Loosen the ignition coil fixing bolt.● Disconnect the ignition coil wire.● Remove the ignition coil.● Install in the reverse order of removal.·Arrange the cords in the right place.
