 GEAR CONTROL INSPECTION
 Remove the seat. (Refer to the chapter 2)
 Disconnect the ignition unit coupler and
 remove the ignition unit.
 Disconnect the change gear control coupler
 and remove the change gear control.
 Measure the resistance between the
 terminals using the electric tester.
· Due to the semiconductor in circuit, it is
     necessary to use a specified tester for
     accurate testing. Use of an improper
     tester in an improper range may give
                                                                                    Ignition Unit
     false readings.
   · Use a YF-3501 Electric Tester.
   · In this table, "Needle swings then               Ignition Unit
     returns" indicates that there is a charging
     current applied to a condenser. The needle
     will then remain at "" unless the
     condenser is discharged.
