Question:

If the green light on the Tekonsha #9030 Voyager Brake Activator, item # 39510, is remaining on when the trailer is not connected to your vehicle it means that the brake controller is sensing a load on the blue brake output wire. Many times when this occurs there is green or white corrosion that has formed inside the trailer connector at the rear of the vehicle. I would check the front and back side connections inside the connector to ensure that the connections are clean and that corrosion has not bridged between two or more circuits.

An easy way to see if there is a problem in the brake controller or on the blue wire past the brake controller is to disconnect the blue wire near the back of the brake controller. If, when the wire is separated, the green light goes out you know there is a problem on the blue wire between the controller and the rear of the vehicle. If the green light remains on, there is most likely a problem in the brake controller itself and, the controller will need to be replaced. Brake controllers do not have user serviceable internal parts.
