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

It sounds like you have everything wired correctly to bench test. To bench test a brake controller you need to connect the black wire from the Tekonsha Voyager Trailer Brake Controller #39510 to the positive terminal of a 12 volt battery and the…

I would be happy to help! Since your Dexter axle has a 7000lb rating you will need the Electric Brake Assemblies #23-464-465 for self adjusting brakes, or #23-180-181 for standard brakes that you will need to adjust on occasion. I recommended the…

Answer 6

In a typical 7-way trailer connector the trailer 12V auxiliary power feed, usually carried on the socket contact at the 1-o-clock position (please see photo), can be ignition-key-controlled or it can be a direct feed from the battery, passing only…

Thank you for being very detailed with your question! The first step I would take is to make sure everything on the truck and trailer is wired properly. Your Prodigy brake controller should have the wiring adapter #3025-P which is custom for your…

Answer 8

I am not entirely sure what process you took so I'll give you some other things to try, or maybe a different way to test the Prodigy P3 #90195. First, sever the blue wire a couple inches from the back of your controller. Then use a circuit tester…

Answer 9

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…

Answer 10

The orange wire you found is the CHMSL circuit. This is the center high mount stop light wire. It is not used by a brake controller so you can tape it up and stow it out of the way. The wires that you will need with be 12 volt power, output to…

Answer 11

No you should not have constant power on the brake output pin, the blue wire should only have power with the brake pedal depressed in the vehicle or the brake controller manual override is activated. If the blue wire has a constant 12V then it is an…

Answer 12

All the brake controller needs to sense a trailer connection so that you can test it is a slight amperage draw on the output circuit. For that you can use a circuit tester like the part #PTW2993 with one pin grounded and the other on the output pin.…
