Pulled 7way plug out of truck.

But there is a fuse that powers the brake controller. He states it does not light up.

Where is the OP with an update?

I would start at the trailer connector and inspect the wiring. Its not Rocket Surgery and is pretty easy to trace the wires and find the break.

If you need to replace the brake controller look at the Tekonsha Prodigy P2, P3, or the Primus IQ. They are fantastic brake controllers.

Thanks!

Thanks Jeremiah,
The controller never lights up. Will it light up when the trailer is not connected to the truck via the long black cord?

I wish I had the proper terminology, then I could better understand how to describe items. When you say "trailer connector" is that the grey box tucked up inside and under the kingpin housing assembly where all the wires connect from the long black cord?

With your brake controller not lighting up at all I think your issue on the vehicle side.

When your trailer connector is connected to the truck the Voyager should be illuminated green. This tells you that you have a good connection.

When I talk about the trailer connector there are two components that I am referring to.

The Truck Side connector (Female 7 Blade RV Connector) and a Trailer side connector (Male 7 Blade RV Connector)

Here is a good page showing a discription of the wiring and a wiring diagram for the 7 way connectors.

Here is a video on installing and using your Voyager. Don't be concerned that this is a Voyager and not a Voyager XP. The function is just the same.

If these do not help, then I would start testing circuits with a circuit tester.

Here is one similar to what I use

Circuit Tester

You have a fiver and I am assuming that you have a vehicle side connector in your bed. Many times you will also have one down close to the receiver hitch. If you do, then you can try to plug in there as well.

As to wire colors...

Typically... the wire that powers the trailer brakes is blue.

HOWEVER, you can't always trust that. Sometimes guys use whatever color wire is available to them.

Thanks and good luck!

look through this link and you'll find the connections you need.

As to the controller, even if the pigtail is not connected to the trailer when you push on the brake it should give you at least one red light..

I would be inclined to start at the vehicle plug and test for 12V current on the brake wire output. It seems to me that the wiring in the TV plug can be "fragile" and subject to become damaged from a sudden jarring. Next up would be to check the continuity of the brake wire in the RV harness by using a tester, one probe in the kink pin box and the other on the appropriate pin of the harness. Good Luck

Cheers!

Thanks Mike,
When you say "TV"plug, is that the trailer vehicle your referring to? If so, I don't have a plug just a bunch of wires in what I call a junction box inside the kingpin housing assembly. Do you know what color the brake wire would be?

I don't know if you have one, but do you have a break-away cable which also became disconnected? I did that in the middle of a turn and it locked up the trailer brakes, as it should... but, was not in a good place.... have a fifth-wheel.

It happens. My cord got caught on a bed bracket and I ripped it out of the trailer. 3 hours of tracing and mending wires as nothing was color coded. I would put a meter or test light on the brake terminals of your truck socket (schematic on internet) and hit the emergency switch on your controller. If you have juice start looking at the trailer.

Check the fuse. It may have grounded out or shorted when it was ripped out.
