If the headlights come on without the engine running (with just the key on), it is a DC system. In the AC system, turning on the headlights requires the engine to be running. Another indication is, if the motor only runs on a battery it is direct current. If it is battery operated, it is an AC system. Package List: 1 x Spark Plug 1 x CDI Box 1 x Ignition Coil
