The ACC line (or Accessory Line) in a motorcycle typically refers to the wiring used to connect accessories or devices that require power but are not directly related to the ignition of the engine. The ACC line is usually controlled by the ignition switch, meaning it provides power only when the vehicle is turned on or in the "ACC" (accessory) mode.
Main Features and Function:
- Power Supply: The ACC line provides power for external electronic devices (such as GPS, USB chargers, audio systems, LED lights, etc.). These devices typically require power only when the motorcycle is running, not when it’s turned off.
- Ignition Switch Control: The ACC line is typically connected to the motorcycle’s ignition switch, ensuring that power is supplied only when the engine is on or in accessory mode, helping to prevent battery drain.
- Prevents Battery Drain: By connecting accessories to the ACC line rather than directly to the main battery, it ensures these devices won't consume power when the engine is off, thus extending battery life.
Common Applications
:
- GPS Navigation: Ensures the GPS system gets power while riding.
- LED Auxiliary Lights: Powers additional lights, ensuring they only turn on when the engine is running.
- Audio Systems: Powers audio systems so they can be used while riding.
How to Find the ACC Line?
On most motorcycles, the ACC line is typically found near the ignition switch or in the electrical junction box. You can use a voltage meter or test wires to identify which ones are the ACC power lines. The motorcycle's service manual will often list this information as well.
If you're adding accessories or modifying your bike, using the ACC line for power is a common approach
