Black vs Red power source

Modified on Thu, 10 Sep at 8:49 AM

Black Power Source (Auto-Switching)

Automatic Switching: Features an integrated voltage sensor that automatically activates power delivery upon detecting approximately 13V (typically reached once the engine is running).
Auto Turn-Off: Automatically cuts power when voltage drops below 13V, preventing battery drain when the engine is stopped.
Connection: Designed for direct connection to the motorcycle battery or to an unswitched ("always-on") auxiliary supply.

Safety Note: When connecting directly to the battery, always install an appropriate inline fuse.

Red Power Source (Always-On)

Continuous Power: Operates without a voltage threshold sensor, supplying power continuously as long as input voltage is present.
Connection: Designed for switched circuits (ignition-controlled auxiliary power / ACC circuits) where power turns on and off with the ignition key.

Choosing the Right Power Source

Select the Black Power Source if connecting directly to the battery or an unswitched circuit and you require automatic shut-off when the engine stops.
Select the Red Power Source if your motorcycle has a dedicated switched auxiliary/ACC circuit controlled by the ignition key.
