Checking the Car-Battery Adapter



Checking the Car-Battery Adapter

NOTE: There are several types of adapters but the checkout procedure is the same for both of them.
  1.  Unplug the Car-Battery Adapter cable from the computer.
  2.  Plug the Car-Battery Adapter into the cigarette lighter socket.

    NOTE: If the adapter is already plugged in, reseat it.

  3.  Measure the output voltage of the Car-Battery Adapter cable.

     

    Pin Voltage (Vdc)
    1 +19.0 to +21.0
    2, 3 Ground

     



NOTE:
  1.  If the output voltage from the cigarette lighter socket of the  car is less than 10.5 Vdc, the power-on indicator on  the Car-Battery Adapter blinks and a continuous  noise can be heard.  The condition of the car battery  should be checked by appropriate service personal.
  2.  The Car-Battery Adapter does not support operational  charging.
