Expert Answers about Ram 2500


  • Ram 2500 Vehicle Side Wire Failure
  • You have isolated the issue to the truck and already checked the fuses and the trailer connector. If you haven't used your owner's manual to check all the fuses and relays for towing just to be sure. Next, I would check that the ground connection is good and clean as well. It needs to be grounded to bare metal. If this checks out, the problem is on the wiring itself. If you follow the wires from the backside of the 7-way, there is another connector that the trailer harness plugs into....

  • Will InfiniteRule Locking Pins Back Off On Road
  • We haven't had any issues with the InfiniteRule Locking Pins part # IR57RR coming loose so I wouldn't anticipate that being a problem at all. When these are in the locked position they actually can't thread on or off.

  • Troubleshooting MaxxAir Fan Issue with New Motor
  • It sounds like your MaxxAir MaxxFan Trailer Roof Vent has a powered lift like # MA00-04500K but has a connection issue. It is getting power for the lid to open and close but not for the fan function. I recommend testing your wiring using a circuit tester like # PTW2993 to make sure you are getting power to your fan switch and if so if power is getting to your new motor. If you test the motor with a battery and it works, then you know you have switches or wiring that is in need of repair....

  • Solution for Demco Hijacker Autoslide Hitch Latch Won't Stay Out
  • If the handle of your Demco Hijacker won't stay out when you are trying to disconnect from the trailer Demco recommends installing the safety pin in the second handle hole just outside of the frame handle bushing to hold it out so that you can basically lock it in the open position.

  • Troubleshooting A 2011 RAM 2500 Giving a Service Trailer Brake System Error
  • I did some research and it turns out that this error is fairly common amongst RAM owners. What this error is saying is that there is a problem with the ITBC (Integrated Trailer Brake Controller) system. My guess is since you're using an aftermarket brake controller and not the OEM brake controller the system might be a bit "confused" for lack of a better term, especially since the brake controller is working just fine. I'd recommend taking it to a local RAM dealer and see if they can...

  • Troubleshooting Brake Controller Function on 2012 Ram 2500 with Custom Wiring Harness
  • Since your trailer lights are working, it sounds like you have simply blown a fuse. I recommend checking fuse J02 (30 amp pink cartridge fuse) in the engine bay fuse box. If this isn't the issue, then I recommend using a circuit tester like # PTW2993 to test your brake controller functions. I have also attached some help articles on troubleshooting installation connections.

  • Troubleshooting Trailer with Brake Lights But No Turn or Running Lights
  • That's a very interesting situation because the turn signals should be on the same circuit as your brake lights. Since your 2019 Ram 2500 is pretty new I think the issue is on your trailer, but it would still help to test the connector on your pickup with a circuit tester like part # PTW2991 to ensure you are getting power to your trailer. I have attached photos of which functions should be located on the different pins for both a 4-Way and a 7-Way connector. If you don't get all of those...

  • Troubleshooting Slide In Truck Camper Battery Draining When Being Towed By 2019 Ram 2500
  • That is a strange issue to be having. I would start out by checking your truck camper to determine if the battery discharge is being pulled by the camper or is the truck pulling the charge from the camper. If the camper battery is being drained by the camper then you will just need a Charge Line Kit # RM-156-25 to run from the 7-way in your bed to the camper battery. This should allow the battery to charge off your 2019 Ram 2500 when it is running. In the event battery power is somehow...

  • Fuse Keeps Blowing on 2017 Ram and Running Lights on Trailer Do Not Work Properly
  • It sounds like you have a short somewhere on your circuits. You can start by inspecting the 7-Way connector on your 2017 Ram and your trailers to make sure that they are clean and do not have any debris in them. If those look good then the next step would be to inspect all of your grounds and make sure that they have a solid connection to a clean, bare metal surface. Even some paint could cause a bad ground which results in a short. Since this problem is happening with both trailers...

  • Troubleshooting Timbren Springs Contacting Axle On a 2017 Ram 2500 With No Additional Load
  • The Timbren Rear Suspension Enhancement System # TDR2500D that you have for your 2017 Ram 2500 4X4 with the factory air suspension is designed to fit a vehicle with good suspension and vehicle lift or lowering kits. You should have 1/2" to 1-1/2" of clearance between the Timbren springs and your axle with your Ram unloaded. Seeing as your springs are touching with no weight you either have some kind of lowering kit on the rear of your truck to level it out or your springs have worn to the...

  • Troubleshooting Trailer Charge Line Draining Battery On 2020 Ram 2500 When Ignition Is Switched Off
  • You will want to contact your local Ram dealer to determine if there is a ECU Flash which will fix the issue of the charge line sending power when the ignition is switched off. I do know this was an issue with older Ram trucks and the only way to resolve this was by installing a Relay # BDW42035 in line of the charge line. This will allow you to connect the switched side of the relay to an ignition source so power only flows through the charge line with the ignition switched on.

  • Troubleshooting Solid Red Light on Lippert Replacement Controller V-Sync II
  • If the controller you have is the part # LC211852 that is showing a solid red light that would indicate the controller is bad since that is not a standard fault code. You would need to replace it with the # LC211852.

  • Troubleshooting Trailer Running Light Signals from 2015 Ram 2500
  • Since you have changed out any blown fuses related to trailer lighting in your 2015 Ram 2500 I suggest you test the truck wiring without the trailer connected. This will help you isolate the problem to either the vehicle or trailer side. Please refer to the linked photo (and article on trailer wiring) which shows the function carried on each pin of a 7-way vehicle socket. Running light power is carried on the 7-way contact at the 11-o-clock position as you look at the socket from the back...

  • Troubleshooting Curt Gooseneck Hitch Ball Stuck in Bed of 2016 Ram 2500
  • The Curt Underbed Gooseneck Trailer Hitch for Ram 2500 # C60614 sounds like the hitch ball has been damaged. I recommend first using a penetrating oil like the UltraLube Biobased Spray Lubricant and Penetrant - 12-oz Aerosol with Straw to spray into that hitch ball lever and also around the edge of the hole on the top and bottom. Use a little vibration from a rubber mallet to let the oil find its way into all the bound locations. Let sit for a few minutes and then try again. Repeat...

  • Fitment of Reese Sidewinder 5th Wheel King Pin with Rotating Turret 20k
  • A lot of play or little play in your Reese Sidewinder # RP77FR can be subjective to the observer. Either way, if there is enough movement to cause you concern, as it apparently does, then that is enough reason to investigate. Please examine all bolts and connecting points for fitment and consider taking to an RV shop for a look over if you do not find anything but still have concerns. Verify that you are using the correct wedge for your Sidewinder and 5th Wheel Hitch. To tell you that...

  • How to Check for a Short forTowing a Gooseneck Trailer with a 2016 Ram 2500
  • If your pickup is the 2016 Ram 2500 that you chose for the fitguide then it is very unlikely that the issue is with your truck. Changing the 7-Way connector on your gooseneck trailer was a great starting point but it does sound like you are correct about there being a short. Checking the wiring on a trailer for a short is fairly tedious but it isn't very difficult. Essentially you just need to inspect the wiring for any places where the wiring looks damaged or pinched and then replace...

  • Display Not Working on Lippert Ground Control Leveling System
  • The good news is your system is working. That lets us rule out 2 of the 3 possible components. Before replacing the third one, I recommend unplugging the connections on the panel and cleaning them prior to reconnecting. If this doesn't solve your problem, then I recommend the Replacement Auto Level Control Panel for Lippert Ground Control Leveling System # LC421484 to give you the working LCD display.

  • Troubleshooting An Everchill RV Refrigerator That Isn't Maintaining Temperature
  • If your Everchill RV Refrigerator w/ Freezer Drawer # WAY44FR isn't maintaining the proper temperature then you most likely have a clog in the condensation line choking the fridge up and preventing it from properly cooling. I recommend pulling the fridge out from the wall and cleaning out any dust build up and and cleaning the condensation drain line so that the fridge can breathe. I also recommend checking the voltage at the unit to ensure it's receiving enough power to properly operate.
