Description

This Blue Line AC CDI is an affordable aftermarket replacement for a failed ignition module on compatible GY6 and 139QMB scooters, helping you get your scooter running and enjoy the ride again. Its compact black housing and separate two- and four-position connectors suit matching AC-powered ignition systems.

Key Features

  • Practical ignition repair: Replace a faulty CDI without paying for an unnecessary performance upgrade.
  • AC ignition application: Designed for matching alternating-current CDI systems, not DC-powered systems.

  • Compact housing: 65 × 37 × 23 mm body dimensions help you check mounting clearance.
  • Broad replacement applications: Fits the specified Chinese GY6 and 139QMB configurations when the ignition type, connectors, and pin assignments match.

Confirm that your scooter uses an AC CDI before ordering. Match the connector shapes, terminal positions, wiring assignments, and mounting clearance to your original module. Similar connectors or an engine code containing “QM” or “FM” do not establish compatibility by themselves. This unit is not a replacement for a DC CDI.
