About the Catalog

AC or DC?

  • Most older machines are AC.
  • Most newer machines are DC.
  • 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.

For more information about CDIs, see the Wikipedia page.
