      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      L43-7 (SS1) - L43-5 (GND) Pushed Below 1 Ω
      L43-2 (SS2) - L43-5 (GND) Pushed Below 1 Ω
      L43-7 (SS1) - L43-5 (GND) Not pushed 10 kΩ or higher
      L43-2 (SS2) - L43-5 (GND) Not pushed 10 kΩ or higher

      If the result is not as specified, replace the power switch.

    2. Apply auxiliary battery voltage between the terminals of the switch, and check the illumination condition of the power switch.
