Question about 2002 Ford F250 Super Duty SuperCab

1 Answer

Trailer breaks not working on 2002 Ford F250. Trailer brakes are good and have a new break controller. I do have voltage on the 7 pin connector when break is applied, the voltage starts at about 9 volts and goes down to about 3 the longer the brake is held. I would think if there was a short or open there would be 0 voltage? What can cause my trailer brakes to not work?

A faulty conection ( rust, corroded,loose etc) can let voltage through but not proper amperage to energize your brakes

I have a 96 ford explorer xlt with a hidden hitch. the 7 pin rv connector is not working. i found where the wires from vehicle connect to 7 pin connector and one wire was caroded at the crimp black wire...


Yes, you need the other wires to provide the trailer with battery voltage. If the trailer has trailer brakes, you should have an RV mechanic wire up the connector so the brakes on the trailer operate from the Ford.

Trailer signal lights don't work or break lights. trailer breaks work fine ??????????


Is there voltage at the truck connector? If not, check the fuse. If the fuse is OK, then check the condition of the wiring. I see trucks all the time on the road with dangling wiring harnesses, and it is very common for the wiring to get damaged. Good luck.

If these lights still work on your excursion then it is probably not a fuse problem. It sounds like it is a loose pin(s) with the trailer plug or a loose electrical connection(s) on the trailer or maybe the bulbs on the trailer are burned out. This should help, if not then contact me again at FixYa and I will be glad to help.

Go to your fuse box in the engine compartment. Check the fuses in the box. Your turn signals and brakes to your trialer are controlled fron fuses in that box not inside the truck!

I do not have power on the aux. terminal in the trailer plug on a 2008 dodge ram. Any ideas?


You have got 7 pin trailer connector that was included in the optional trailer tow package. This trailer tow package also includes an electric trailer brake wiring provision that terminates at a connector located on top of the large body harness connection under the instrument panel to the left of the break pedal, as well as an electric trailer brake pigtail harness and an instruction card that are stored in the glove box when the vehicle is shipped from the factory. You will need to add an electric brake controller of your choice that will plug-in to the harness and that will also give you power on your auxiliary circuit.

Brake controller not communicating w/ 7 pin connector


what type controller did you install? Is this a camper or trailer? Is the controller hydraulic plumbed into master cylyder? Important to know how to adjust rheostat for sensitivity. If set at minimum the system is basically on the edge of not sending any signal to towed unit. The intructions should explain how to make this adjustment. If set too sensitive trailer brakes will lock up before the tow vehcle starts to brake. Controller should be set so trailer starts braking just befor the tow vehcle. If not the trailer will tax the tow vehicle brakes by pushing. Its set right when you feel the combination stretching out. trailer first then tow vehcle. Good luck and remember, if truck brakes first and too hard you risk a jacknife. All light voltages should be system voltage. Brake voltage is variable depending on setting on controller. Understand your breakaway brakes and how they work. breakaway breaks require an auxillary battery. Again, good luck and you know where to find me if I can be of anymore help.

2004 F250 No brakelights/turn lights on trailer


You will need to get a 12 volt test light and check the trailer connector for a voltage signal to the trailer, it may also have seperate fuses under the hood for the trailer lights if the system is factory installed, federal law requires the 2 systems be isolated, if there are blown fuses find the short in the trailer before replacing fuse(s), with no exceptions the short is always in the trailer. Hint, check the fuses 1st.
