Chinese Scooter CDI's

AC or DC?

  • Most machines (especially the newer they are) are AC.
  • DC CDI boxes are larger than AC CDI boxes.
  • The easiest way to tell if your machine is AC or DC is to turn on the headlights with the machine turned off and the ignition in the "ON" position. If the headlight comes on, it is a DC machine; if it does not, it is an AC machine.
