  • Roadmaster Automatic Battery Disconnect is Disconnecting Battery when Vehicle Turning Off Ignition
  • I reached out to my contact at Roadmaster because I have not heard of this particular issue happening before with the Automatic Battery Disconnect # RM-766. He said it's possible that something is going on with the switch itself and there is an easy way to find this out for sure. There is a small 7.5 amp fuse at the end of the "Battery Post" cable, which is for the switch. With the unit running and on, remove this fuse to cut off power to the switch. Then start your vehicle and turn it...

  • What Does Curt Echo In-Line Brake Controller Pull Power From
  • The Curt Echo In-Line Wireless Brake Controller # C79DR is designed to be plugged in-line with your USCAR connector that pulls power from the 12 volt power pin. It is designed to be used with a standard 7-way and not a commercial 7-way. The pin-outs are different on a commercial 7-way, so my best guess is it is trying to pull too much power from that pin when using the manual override and that is causing the issue. You may be able to remedy this by re-pinning your commercial 7-way so the...

  • Troubleshooting Trailer Wiring 4-Way Where Running Lights Don't Work
  • First thing to try is clean the pins of the 4-way on your Focus and trailer. Most likely it's just a bit of corrosion that needs to be cleaned off that's preventing the circuit from being connected. Typically sandpaper takes care of this the easiest. To test the converter box you can use a circuit tester like the part # PTW2993 to test for voltage going into the box and coming out with the running lights are on as well.

  • Losing Power Of Curt Custom Wiring Harness # 118674 On My 2016 Ford Focus
  • There isn't a reset switch on your T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, # 118674. If you aren't getting any power, you will want to check the in line fuse first. If that is still good, you will want to check the connection at the battery for any issues like corrosion or noticable wire damage. If there is any damage you'll want to replace the wire. If there is still no power at the unit, use a circuit tester, like # PTW2993 to check individual functions. ...

  • 2008 Ford Focus Turn Signals Blink Faster when Connected to a Trailer with Wiring Harness 118457
  • When the trailer is connected and you use the turn signal, or any of the lights, there is more power draw on the vehicle system and that might be leading to the blinkers going faster. Also check the main ground for the wiring harness # 118457, just to be sure you do not have a developing ground issue. Check the trailer lights to determine how much amperage they draw for each function. Then check to see what the tail lights on the vehicle can handle. You do not want to overdraw the wiring...

  • Would Performing a Battery Test Fry a Trailer Wiring Harness on a 2012 Ford Focus
  • If the yellow fuse holder wire from wiring harness # 118549 was pulled out at the battery then it would not have done anything to the converter box. What might have happened is some part of the system when attached to the battery touched something else and melted or burned something but that is speculation. The trailer lights get the power from that connection to the battery so if it is not connected or the fuse is blown then it will not work. If it is all connected and the lights are...

  • Trailer Running Lights Lit All the Time w/Curt Trailer Wiring Harness Installed in 2013 Ford Focus
  • Does your trailer happen to have LED lights? If so then what is happening is the little bit of power that is on wiring harness # C56138 is enough to dimly light up LED lights. This is because the wiring harness is a powered harness and LED lights draw such little power. We hear about this issue less with the Tekonsha harness # 118548. It is also possible that there is a short drawing power. Make sure the trailer connectors are clean and free of corrosion. Also check the wiring on the trailer...

  • Troubleshooting A Roadmaster Even Brake Motorhome Monitor That Can't Be Reset
  • I spoke with Roadmaster about your issue with your RoadMaster Even Brake Motor Home Monitor # RM-9410, and they mentioned that if you have already plugged it in an unplugged it and there's still an issue, then there is a fault circuit board issue and the whole unit would need to be replaced. I know that's not ideal since you have just received the new monitor, however this is going to be the best solution for you.

  • Troubleshooting Excessive Tire Wear on a 2007 Ford Focus when Being Towed by a Motorhome
  • There are several possible causes for the severe tire wear you are seeing on your Ford Focus. First, if the tow bar is not level with the RVs it can put extra stress (downward force in this case) on the front of the Focus. That extra force can lead to not only tire wear but also potentially damage the tow bar and base plates. Make sure that you have the steering on the Focus unlocked so that it is free to turn when being towed. If the steering is locked, it will cause severe tire wear...

  • Troubleshooting Trailer Wiring 12 volt Power Circuit of a 2014 Hurricane Motorhome Not Working
  • It could be a fuse or a relay that you burnt out in your 2014 F-53 Hurricane Motorhome. I would recommend you check the owners manual of the MH to determine where all of the tow package fuses and relays are and check them. It can be hard to determine if a relay is bad. If you find the relay for the circuit that is not working but are unsure if it is bad the easiest way to test it is to put a good working relay in its place and if the circuit works at that point you know the relay was bad. I...

  • Can Roadmaster 8700 InvisiBrake System Make Beeping Noise in Engine Compartment
  • The only 2 things the Roadmaster InvisiBrake # RM-8700 has that makes an audible noise is the air compressor and the motorhome monitor that lets you know if the brakes have been activated too long. I spoke with my contact at Roadmaster who confirmed that nothing with their system makes a beeping sound. Since this is the case the Ford service department you went to either doesn't know much about the vehicle or they were just trying to move on to the next customer. I would take your vehicle...

  • Kuat Trio on Thule AeroBlade Bars Does Not Clear Spoiler/Open Hatch on 2016 Ford Focus ST
  • We can't have that happening! Let's see what we can do. Roof bike racks such as the Kuat Trio # RU01 are designed to fit roof racks and not specific vehicles. Even if the rack was not touching the spoiler on your 2016 Ford Focus ST with the hatch open the rear bike tire most likely would have. How close is the rack from being able to clear the spoiler? If it just barely touches then it would be permissible to move all 4 of the roof rack feet forward a hair so that it doesn't touch. But...
