• Voyager Brake Controller Indicator Light Goes from Green to Bright Red and Doesn't Change
• The Voyager brake controller # 39510 is sensitive. If even slightly off level it will misbehave. First, make sure the controller is mounted within the ranged specified in the instructions. The controller cannot be tilted or turned to the side either. If mounted outside its range or tilted/turned it can cause this issue. The controller might also be sensing a short. Check the vehicle and trailer side connectors and make sure they are clean and free of corrosion inside where the wires attach...

• Troubleshooting Trailer Taillights That Only Function on One Side of the Trailer
• Since all of the wiring problems are on one side of the trailer that leads me to believe the problem is in the grounding of the light assembly on that side of the trailer. A lot of light assemblies ground through the mounting hardware. You will want to make sure the assembly is connected to a clean metal surface. I attached a couple FAQ articles that should be helpful as well.

• Troubleshooting a 1999 Ford F250 that Lost Interior Lights, Dash Lights and Running Lights
• Brake controllers draw a considerable amount of amperage. What I can almost guarantee happened is when you hit the override lever of the controller you overdrew the running light/head light circuit you used to power the brake controller. Once you determine what has shorted out on the truck I would strongly recommend you change the wiring of the brake controller so that it is powered straight off of the positive terminal of the battery through a circuit breaker like part # 9506P. Pull the...

• Trailer Drivers Side Tail Light Not Working, All Other Lights Work
• This sounds like a ground issue. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds should also be attached to clean and corrosion free bare...

• Troubleshooting Dash Light that Came on a 2012 Mazda CX-9 after Brake Controller Install
• If the light on your dash indicates something is wrong with the engine, then the installation of the P3 part # 90195 would not be related. If the light on your dash indicates something about taillight circuits then it would be related to the stoplight circuit you used for installation of the controller. If the taillight no longer illuminates that would indicate that maybe you accidentally cut the circuit of the light when you tried to tap into it opening the circuit. Either way you could...

• Trailer Riding High At the Trailer Hitch on a 2007 Mazda CX-9 With Weight Distribution Installed
• You may need to adjust the ball angle on the weight distribution system to level the spring bars with the trailer frame when the unit is hooked up. I have included a link to the instructions for the Reese Heavy Duty Round Bar Weight Distribution System, # RP65509. The instructions you need start on the top of page 2. If the trailer still is not level after making the above adjustments, you may need to lower the ball mount for a level ride, especially since you stated that your tow vehicle...

• Troubleshooting Installation of Curt Hitch # C13315 on a 2016 Mazda CX-5
• Sorry to hear about your hitch! Yes, we have heard of this issue before. I went ahead and confirmed with Curt that the # C13315 definitely fits your 2016 Mazda CX-5. The most likely explanation of this situation is that the hitch bent during transport. This can cause the bolt holes to potentially not line up when you try to install the hitch. There are multiple ways of bending the hitch back into shape via a vice, an open step, the floor, against a wall, or with a jack. I went ahead...

• Backup Light Fuse Blows When 1990 Mazda B Series Pickup Shifts Into Reverse
• A 4-pole wiring harness carries stop, turn and tail light signals only, and does not connect at all to a vehicle's reverse light circuit. Since this custom harness uses connectors specific to your truck and simply plugs in, it sounds like there could be a short caused perhaps by a damaged connector on the vehicle. This could account for the harness interacting with the truck's reverse light circuit. Given the truck's 26-year age it is quite likely that the issue is simply corrosion in...

• Curt TriFlex Brake Controller AE Error that Caused Error Messages on a 2016 Mazda CX-5
• The first thing you will want to do is have the error codes showing up on the vehicle cleared by a mechanic. When a vehicle throws codes like that they stay in the computer memory so disconnecting the controller won't stop the error messages from appearing. It does sound like something may not have been hooked up quite right but it could also be an internal issue with the controller (more on that below). On the 2016 Mazda CX-5 there isn't a plug-in harness for a brake controller so it...

• Method to Reduce Wind Noise from Roof Rack on 2014 Mazda 3
• Roof rack crossbars do generate noise and some make more noise than others. Round and square bar roof racks tend to be the noisiest and elliptical and aerodynamic bars tend to make less noise. No roof rack will be particularly quiet when you have your sunroof open. That is just the nature of the beast. You can sometimes reduce the noise level of a roof rack by adding a fairing to the front bar, such as Inno's # INA262. These usually help the noisier round and square bar roof racks like...

• 2011 Mazda CX-7 Taillights Flicker After Installing Replacement LED-Type Bulbs
• Both the stop and tail light bulbs used on your 2011 Mazda CX-7 are the 7443 type as you noted. We offer this bulb type in both halogen versions like # P217443B (possibly what you had originally) and in LED types like the Putco # P237443R360. LEDs are very high efficiency lights that can sometimes light up from even the low-level residual current in vehicle or trailer wiring. Load resistors that will correct the flicker. Use one per bulb. We offer # DI34ZR.

• Can a Taillight Converter Module Go Bad After Working Properly for Months
• It is possible for a taillight converter module to go bad. If your circuit testing shows correct signal inputs to each input pin of the module, but no output from the module, then the module could be blown. Please refer to the trailer wiring troubleshooting guide attached. This page offers information about the likely causes for a failed module and how to isolate the problem. Any one of a number of issues can cause failure of a module. If the module suddenly stopped working and there...

• Troubleshooting Trailer Lights Not Working Towing With Mazda CX-5
• There can be issues like this on some trailers using LED lights where they don't work at all. More than likely your LED lights aren't drawing enough power and this is the reason the tester works but not the lights on the actual trailer. This also varies between vehicles which would explain why it works on the truck and not your CX-5. In order to simulate more current draw, you can use load resistors like the # DI34ZR. You will need one per circuit so in this case 3 for the right turn/stop,...

• Troubleshooting Driver Side Turn Signal Not Working on 4-Way for 2009 Mazda Tribute
• Since only one function is not working it doesn't sound like it is the converter box. Although there could be a problem with the connectors, there should be no real loss of conductivity over time. It is possible that the # C56329 needs to be replaced, but there are a few things you can check first before going that route. The first thing I would do is double check the connectors. If the connector is not fully seated and came apart over time it could explain why it went out intermittently...

• Troubleshooting Trailer Wiring for Fleetwood Pop-Up Trailer and 2003 Mazda B3000 Pickup
• A potential cause for your issue is a weak ground connection. Trace the white ground wire from your 4-pole back to where it attaches to the vehicle frame. This ground must be secured to a clean and rust-free spot on the frame. If necessary sand off the rust/dirt from that grounding point and reattach the white ground wire or relocate it a new spot. If this does not correct the problem then I suggest you next test your existing 4-pole trailer connector on your Mazda to confirm it is functioning....

• Using CTEK Battery Charger on Older Original OEM Vehicle Battery in Mazda RX-8
• Typical OEM vehicle batteries are usually not the highest grade available and in my own auto ownership experiences 4 or 5 years seems to be the longest an original battery will last before it shows signs of deterioration. Since you don't mention the vehicle age I will presume it is the last model year for the RX-8, which was 2012. At five years old I would definitely suspect the battery is due for replacement. If it is an older model year, then absolutely the battery could be all done....

• Preventing Rattle with Swagman Titan and Draw-tite Sportframe Trailer Hitch Receiver Class I
• It is normal to have a little play between the hitch and your bike rack, and that play is what causes the rattling you are experiencing. If you wanted to reduce that play you could use a the no-Rattle Trailer Hitch Wedge # MPG908. This rack also has a locking anti-rattle device, the Swagman # S64029. I attached a review video for these products for you to check out also.

• Troubleshooting Trailer Wiring When Connecting a New 4-Flat Trailer Connector
• It sounds like you picked up a 5 wire trailer connector rather than a 4 wire connector. A 4 wire trailer connector will only have a white wire for ground, brown for tail lights, green for right turn and stop and yellow for left turn and stop. The red wire on the connector that you purchased is most likely for reverse lights or a trailer with separate turn signals such as a motorcycle trailer. If you do not have reverse lights or separate turn and brake signals, then you can simply tie off...

• No Power on Curt Trailer Wiring Harness on a 2007 to 2012 Mazda CX-7
• Trailer wiring harnesses # C55593 for the Mazda CX-7 will only fit if the vehicle came with the factory tow package. It sounds like your model did not. What you will need to add trailer wiring is a different type of harness, # 118405. It is possible that even if you ran a power wire to the battery manually and bypassed that connector it might still not work. going with harness # 118405 would be the sure thing.

• Troubleshooting Running Light Circuit on Wiring for 2011 Mazda CX 9 Trailer Harness
• The most common cause for some trailer light functions to operate while others do not is a bad ground connection at either the vehicle wiring harness or the trailer-side wiring. This can happen because a weak ground will still allow some current to pass through - say enough for brake lights and turn signals that are not on all the time - but not for other functions like the running lights and license plate light that ARE on continuously. Check that the white ground wire's ring terminal...
