Green Light on Tekonsha Voyager # 39510 is Constantly On

Question:

I installed a tekonsha voyager brake controller on a 2012 Dodge Ram 1500 truck and used a new harness purchased to match the factory connector under the dash. As soon as I plugged in the harness the green light indicator came on and stays on all the time, truck running or not. The brake controller had been used in a previous Chevy pickup. I have read the indicator light should only come on when a trailer is connected. What is the problem I am having? Thanks.

If the Green light is constantly on when you trailer is disconnected then you have a short on the Blue wire somewhere or it has been wired incorrectly. The Blue wire on the Tekonsha Voyager # 39510 is the wire that carries the signal from your brake controller to the 7-Way on your 2012 Dodge Ram 1500 to activate your trailer brakes. If you are using the Adapter # 3021-P to connect it to your Ram then the wiring is most likely shorted somewhere.

Check the pin in the 5 O'clock position (see attached picture) on the 7-Way of your Ram with a Circuit Tester # PTW2992 to make sure that it is working properly. With your circuit tester on the pin you will want to set the Voyager to the highest power setting and then use the manual override switch to see if it is functioning properly. If it is not you will want to check the wire that connects to the pin in the 5 O'clock position (typically blue, but not always) and follow it to the brake controller. Look for any places where it is damaged, exposed, corroded, or even bent and replace it with 10 Gauge Wire # 10-1-1 and Butt Connectors # DW05745-5.

If this doesn't take care of your problem then let me know and I can help you troubleshoot further.
