      *a Tail Cancel Switch Off
      *b

      Component without harness connected

      (Light Control Rheostat)

      Check the resistance.

      Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      6 (TC) - 1 (E) TAIL cancel switch off → on 10 kΩ or higher → Below 1 Ω
      5 (T) - 1 (E) Always 10 kΩ +/-20%
      7 (TR) - 1 (E) Light control rheostat fully turned right → fully turned left 10 kΩ +/-20% → Below 100 Ω

      If the result is not as specified, replace the light control rheostat.

      Check the illumination.

      Apply battery voltage to the connector and check the illumination condition.

      OK
      Measurement Condition Specified Condition

      Battery positive (+) → Terminal 2 (ILL+)

      Battery negative (-) → Terminal 3 (ILL-)

      		 Illuminates

      If the result is not as specified, replace the light control rheostat.
