Troubleshooting a Tekonsha Voyager Brake Controller No Green Light and Full Power all the Time

Question

Question:

On my 7 pin connector, I have battery voltage to #1 pin battery but also have full battery voltage to #3 pin which is the break pin. The vehicle break lights are not on. Ive checked the wiring connectors to the voyager and everything seems correct. No matter how I adjust the controller, I have 14 volts. The green light never comes on.

The green light of your Tekonsha Voyager Brake Controller part # 39510 is to show that the brake controller senses a trailer being connected. If you can't get the green light to come on plus your brake output pin on your 7-way is reading full voltage at all times there is either a wiring problem on the trailer connector or the brake controller itself has gone bad.

Check the trailer connector first. See if you can find any corrosion on the inside or outside of the connector and fix/clean as necessary.

Testing the brake controller is fairly easy. Sever the blue brake output wire near the brake controller leaving enough room to reconnect it and then apply the manual slide. Using a circuit tester like the Quickee Tester, part # 3808, you should get output to the controller side of the wire you severed. If the manual slide activates the trailer brake output wire properly, try the brake pedal. If the brake pedal activates the brake output properly also then the problem is farther back either in the vehicle wiring or on the trailer.

If either the brake pedal or the manual slide are not functioning properly you will need to test the wires going into the brake controller. Make sure you have power entering the brake controller on the black wire. On the red wire you will only want power when the brake pedal is pressed.

If there is power on the red wire before the brake pedal is pressed you have connected the red wire from the brake controller to the wrong circuit. You would then need to find the brake switch wire that has power ONLY when the brake pedal is activated.

If these connections check out and the brake controller is properly grounded then there is possibly a problem inside the brake controller.

I am including a link to a video that will show you how to test the wiring on a brake controller.

Answer 1

You are correct, you should only be getting output when the brake is applied, or the override switch is activated. It sounds like the controller might be bad, but to make sure, you should probably bench test it before tossing it. Use a circuit…

The Grand Design Transcend Xplor 247BH has a gross vehicle weight rating of about 7,000 lbs so the most the tongue could ever weight is between 10-15% of this which is 700 lbs - 1,050 lbs. Therefore, I'd shoot for a system in the middle of…

I looked at pictures of the Prime Time Avenger 27DBS and it does not appear that the frame is more narrow or even wider than any other A-frame. So it should be at the standard 50 degree angle as far as I can tell. That would mean that when…

I have attached a photo for you below which shows how both a vehicle side and trailer side trailer connector is typically wired. I say typically because this is not always exact and so long as the trailer and vehicle side both match it will not…

Answer 6

Brake controllers such as the P3 you referenced #90195 will go into a sleep mode after about 15 minutes of it sensing no movement. If you peek through the window after 15 minutes then it should be in sleep mode. What you are seeing is normal.

Answer 7

You can reset the controller by unplugging it for 15 minutes. However that should not be needed if you just need to adjust the output power. Just use the buttons on the left of the controller to select the output voltage you want. I have included a…
