• Troubleshooting 5th Wheel Trailer Wiring of 2017 Ford F-350 that Stopped Working
• The 5th wheel trailer wiring you have installed on your 2017 Ford F-350 is going to be like the # 41157 which only has two connections that you'll need to check. But since the rear 7-way is working that would indicate that the issue is the connection to the 7-way that's in the bed of your truck that's got an issue. Try unplugging it and firmly plugging it back in so that all of the pins seat firmly.

• Troubleshooting Reverse Lamps Installed on Dump Trailer Pulled by 2000 Ford F-350
• The first thing I'd check is the center pin on the 7-way connector on your truck to make sure it's active and powers up when the transmission is placed in reverse. If it's not, you might have a missing or blown fuse. One fuse is located in the panel under the steering column. Check the 10A fuse in location 28, and install or replace as needed. The other fuse and relay is located in the distribution box in the engine compartment which is located near the brake master cylinder that sits...

• Troubleshooting Hydraulic Pump of Auto Leveling System on 2014 Heartland Bighorn
• I reached out to my contact at Lippert who makes the hydraulic leveling unit on your 2014 Heartland Big Horn. They send the unit to the manufacturer with a 50 amp auto-reset circuit breaker. The manufacturer installs the wire, etc, so the gauge of wire may not be large enough for the system depending on the run, but that auto-reset breaker will also wear down with use and trip more easily as time goes on. This is likely what is happening, so I would start with the new breaker # PK54250. If...

• Does Air Need To Be Released To Uncouple Hitch Ball From Reese Goose Box
• I spoke with Reese about the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter part # RP85FR and they informed me that you should not have to release any air from the bag to release the hitch ball. There are not any adjustments that can be made to the release cable but if you are having issues with the hitch ball releasing then you may want to add some hitch ball grease part # 58117 to the top of the ball and also be sure when you are uncoupling the trailer you are sitting...

• Troubleshooting Tandem Axle Trailer With 12k Dexter Axles Wearing Inside Of Tire
• There are a few things that could be causing one side of your tandem axle trailer with 12k Dexter Axles to wear the inside of the tire on one side. First you will need to check all of the hardware that secures your suspension components for oblong holes that indicate wear that could be causing the axle to be misaligned, and visually inspect the leaf springs and equalizers for wear. You will need to replace any worn components. Next you will want to make sure that your trailer is not being...

• Compressor Does Not Stop Running After Meeting Inflation And Deflation PSI Setting
• It sounds like you may have a leak somewhere with the connections on the Air Lift WirelessAIR Compressor System for Air Helper Springs - Remote - Bluetooth - EZ Mount Item # AL74000EZ. I would start by checking all of the fittings with an airline. Add about 70psi in your bags, take some soapy water and spray each of the fittings. Look for small bubble to form around the edge. If small bubble are forming, release the pressure, remove the the tube and re-cut the end. Make sure it is not cut...

• Troubleshooting Trailer Running Lights Not Working Behind 2011 Coachmen Freelander RV E-350 Chassis
• As your 2011 Coachmen Freelander is on a Ford E-350 chassis the fuses are in a different location than the F-350 in the Q&A you found. In the engine compartment there is a power distribution box with high current fuses/relays. Relay # 6 is for your running/parking lights for the trailer. There is also a 20-amp fuse in the # 57 position for this circuit. If all these circuits are good you can test for power at your 7-way using a Test Light # PTW2993. Looking into the 7-way the running...

• Why Is My AirLift WirelessONE Blowing the In-Line Fuse On My 2020 Ford F-350?
• It sounds like you may need to check out your wiring on your Air Lift WirelessONE Compressor System for Air Helper Springs # AL25980. Considering that it worked fine before, and now blows fuses that leads me to believe your wiring is the issue. It could also be a bad compressor, but I would first make sure that your wiring is good. Check to make sure that your grounds are clean, (free from rust/debris) not loose, and there are no exposed wires. If your wiring is good, check next to make...

• Troubleshooting Trailer Brake Module Fault on 2022 Ford F-350 with Factory Controller
• It sounds like you may have a short in the wiring on your 2022 Ford F-350. You can use a Multimeter # PT29ZR to check this at your 7-way by checking for continuity with the brake wire and any other wire on the 7-way. You can see the terminals in the image below. As this is a factory controller I do recommend checking with your local dealer as well to determine if there is any required re-flashes needed for the factory controller.

• No 12 Volt Power at 7-Way on a 2017 Ford F-350
• In order for the 12 volt circuit on the 7-way in your 2017 Ford F-350 to receive power, you will need to activate this in the information center on your dash. Please note that once this is done the 12 volt circuit on the 7-way will still not show power until the trailer is connected. If you have activated the 7-way in the information center and are testing the 12 volt power while a trailer is connected and still not getting a reading then you may want to check the fuses in your fuse box...

• Trailer Taillights Not Functioning, Reading 3.5 Volts at Trailer Connector
• The typical culprit would be a dirty or damaged trailer connector. Especially if the truck is more than a few years old. Take a look at the pins in the connector. If you see any white or green corrosion on the pins, there is the potential that the corrosion has spread to the interior of the connector and is interfering with the signal from passing through the connector. The # HM40975 would make an excellent replacement.

• Troubleshooting Kwikee Steps Not Responding to the Override Switch
• The correct replacement control for your 1510000140 step control is the Replacement Control Unit for Kwikee # LC363985. Since most of your functions seem to be working correctly, I would start by checking the 4-way connector before replacing the control unit, it is likely you have a malfunction with the door switch, power switch or wiring. It sounds like your motor is working fine, if your 4-way connector checks out then it could very well be a control issue. It sounds like you are pretty...

• Ford F-250 12v Circuit on 7 Way Trailer Connector is Not Powering Up Unless Truck Is Running
• If your 2016 F-250 has the "smart" tow connector, the 12 volt power circuit on the 7-way has to have the key on to activate. Because of the "smart" tow setup, you have to connect to a trailer and do a setup on the info setup that includes naming the trailer to allow it to be sensed and have the circuit activated when plugged in. In this case easiest solution is run a 10 gauge wire like part # 10-1-1 through a breaker part # 9510 from the 1:00 pin of the 7-way to the positive post of the...

• Troubleshooting Lippert Turning Point Pin Box Having Issues Getting Hitched To B&W Patriot
• Since the wedge you have worked correctly the first time you connected your Lippert Turning Point Pin Box to your B&W Patriot 5th wheel hitch # BWRVK3200 then I would indeed go ahead and loosen/uninstall the wedge and reinstall it. You said you are using the correct wedge so I am assuming that you have the Lippert Turning Point Wedge # LC79UD, so you will want to make sure you have the wedge pointed the correct direction to best keep the king pin from rotating in the hitch, and will want...

• Slider Handle on Curt A20 5th Wheel Hitch # C16541 is Difficult to Pull Out
• If the rails that Curt trailer hitch # C16541 is sitting in are not square that could be causing some issues but it probably would not have much affect on the slider handle. If the rails aren't square then the hitch would not easily slide. If it does slide just fine then squareness would not be the issue. We have one of these set up in our show room so I went to see how it functioned. Pulling the handle out does take a bit of force but nothing that should give you a hernia! The handle...

• Troubleshooting the Demco Recon Gooseneck-to-5th Wheel Trailer Hitch Adapter Turning
• From your pictures, it looks like you have a plastic bed liner in your 2004 Ford F-350. The Demco Recon Gooseneck-to-5th Wheel Trailer Hitch Adapter # DM8550045 requires that the hitch have direct contact with the truck bed and cannot be installed on top of a plastic bed liner. This is likely what is causing the hitch to turn. You will need to either remove the bed liner or cutout the part of the bed liner the hitch sits on and then ensure things are still properly torqued.

• Troubleshooting Truck Bed Cargo Camera on 2016 Ford F-350 with Factory Screen
• For your 2016 Ford F-350, the Truck Bed Cargo Camera for 8" Factory Monitor - Switch Kit # 3460006 is the correct fit. I reached out to their tech and he said since you are getting the switch over to a black screen it simply sounds like you aren't getting 12v power to the camera for it to sent the signal back. You will want to use a circuit tester like # PTW2993 to test the black power wire going to that camera and then trace that wire to determine why power is not getting to the camera....

• Troubleshooting Trailer Running Lights Not Working When Hooked Up to Truck
• The running lights can go by a few different names in the manual; running, tail, or even park. It looks like the number 22 slot uses a 15A fuse for your park lamps that you can check out, but that would be for your 2010 F-350 lights. If those lights are okay and it's only your trailer lighting that's seeing the issue then what I recommend doing is using a circuit tester like # PTW2979 to test the running light pin on the socket for your F-350. If that is showing power with your headlights...
