• Is Wiring of Kat's Circulating Tank Heater Adequate for Amperage Draw
• I'm really sorry to hear about your vehicle catching on fire. I can't even imagine how stressful that would be. I ran this by a guy who was an electrician in a past life though and for the 12.5 amps that this heater draws 10 gauge wire would be more than adequate.10 gauge wire at 12 volts can pretty easily handle 30 amps so 12.5 amps would be no problem at all. He thought that there must have been a short that caused the fire. This could have been due to an issue with the heater potentially...

• Troubleshooting 7-Year Old RV Backup Camera Suddenly Not Working
• I'm sorry to hear about your camera issue! You didn't mention which brand/model camera system you have, but the first thing I'd do is disconnect the camera from power for 30+ seconds to hard reset it. Once that's over just rehook power and try to pair again. If that doesn't work then you'll be needing a new camera. If you can send me the brand and model number of your system I'd be happy to see if there's a replacement camera available, but with the age of the system there's a good chance...

• Troubleshooting Trailer Running and Brake Lights Not Working After Installing New Running Lights
• Brake lights and running lights are not powered via the same wire. Since you're having multiple circuits have issues I'd double check that your hooked up the main ground on the frame, and that no grounds were removed. If grounds check out you'll have a wire coming from each running light that gets attached to the running light circuit on your trailer connector. Some lights ground through the mounting hardware so if your lights don't have a ground wire make sure you attached them to clean...

• Why Wouldn't Brake Controller Work with Brake Pedal
• If you have a brake controller setup that doesn't work with the brake pedal that means there's an issue on the red wire of the brake controller wiring. Sometimes it's as easy as a blown third brake light fuse so you might check there first. It can also be the connection of the red wire to the vehicle wiring as well so check that. Also make sure the circuit the red wire is connected to is a circuit that sees voltage only when the brakes are applied.

• Troubleshooting Trailer Lights Not Working When Head Lights Turn On
• Typically when this happens after installing a wiring harness like the Curt # C55379, it's down to one of two causes. You'll want to start by checking the ground connection on the vehicle and trailer wiring harnesses. Make sure that these are connected to a paint, rust and debris free spot on the frame. You'll also want to check for potential shorts on the wiring, where there might be bare wiring touching a metal spot on the vehicle or trailer frame. The less likely cause would be too...

• MaxxFan MA00-07500K RV Roof Vent Fan Beeps and Closes When Turned On
• I spoke with my contact in the engineering department at Airexcel, the manufacturer of your MaxxFan. The logic board on your fan simply needs to be reset. To do this, remove the fuse or turn off the breaker on the circuit feeding the fan for about 5 minutes, then power it back up. This will reset the fan, and it should operate properly at that point.

• Trailer Brakes Locking and Grabbing when Using a Tekonsha Voyager 9030 Part # 39510
• The first thing to check would be the sensor and power settings on the Tekonsha Voyager. If those knobs get bumped the sensor level can be offset and the brake controller will think you are braking harder than you actually are and end up sending more current to the trailer brakes than needed. The power knob could have gotten turned as well which would cause the brake controller to act more aggressively. If the brake controller it self has been bumped tilted about 70 degrees or below -20...

• Camper with Weak Marker/Running Lights on Right Side
• Your best bet would be to trace the running light circuit from the trailer connector all the way back to the lamps. You will want to pay careful attention to the point where the running light circuit for the right side of the trailer splits off from the circuit for the left side. Since the lights on the left side are operating fine, the problem most likely exists in the portion of the circuit after it splits off to power the right-side marker lights. Check for pinched wires or cracked or...

• Trailer Running Lights Not Working On a 2001 Dodge Grand Caravan
• Since your trailer is working correctly with another vehicle the problem most likely lies in the wiring of the Grand Caravan. Turn the tail lights on and use a circuit tester, item # 3808 if needed, to check the trailer connector. If the taillight circuit is not working, you will need to follow the wiring back into the vehicle until you find the converter, the black box that the trailer wiring is coming out of. Test the brown wire on the trailer side of the converter. If the wire is working...

• Troubleshooting Stuck Hitch Ball in Trailer Coupler
• It sounds like your hitch ball is stuck in the trailer coupler and you've removed the ball mount from the hitch receiver on your tow vehicle. With this being the case, I recommend installing the ball mount back into the hitch receiver and then hitting the ball platform with a rubber mallet # PT24FR while jostling the trailer coupler to see if it comes loose. If you have a trailer jack then you can also try lowering the leg while tapping the ball mount with the mallet to see if the jack...

• Constant Voltage on Brake Output Pin of 1999 Ford F-250 with Tekonsha POD Controller
• I'm not totally sure why this is happening in all honestly, if you unplug the Tekonsha POD Trailer Brake Controller part # 39523 does the power go away? If so, check the blue wire for voltage coming from the brake controller, if you get power here without the pedal pressed or the override then you know the controller is bad. If you don't, odds are there is a short on the blue wire somewhere between the brake controller and trailer connector which means you'd have to start tracing and checking...

• PD4560K18LS8 No Output to DC Side
• Per the instructions of the # PD4560K18LS8, if there is no output, there are a number of potential issues. One is the AC distribution panel, one is the reverse battery connection (if they are connected in reverse, even momentarily, they will blow), one is a blown circuit, and another is the output mode switch not being on.

• Troubleshooting Trailer Wiring Where Running Lights and Turn Signal Stopped Working
• It's very possible it's a blown trailer wiring fuse or relay like you mentioned but typically this problem is just corrosion on the trailer wiring pins that needs to be cleaned off and once that's done the connection is allowed to pass through and the problem goes away.

• Troubleshooting Curt Venturer Trailer Brake Controller With Brakes Always Locked On
• The Curt Venturer Trailer Brake Controller # C74VV could be faulty. To find out for sure you can bench test the controller as per the instructions. I have included those below for you to reference. Before removing it for a bench test I suggest checking the red wire that runs to the brake switch. This should only show 12v power when the brake pedal is pressed. If the brake switch is faulty this would cause the brake controller to believe it needs to send power to the blue brake wire. To...

• Troubleshooting a Wiring Harness That is Not Getting Power on a 2019 VW Golf
• This does happen sometimes when installing wiring harnesses and is usually caused by one of three things. You will need to use a circuit tester, like the # PTW2993, to figure out which will be the cause. First, and the easiest, will be to check the fuse in line from the battery to the ModuLite box. These are occasionally bad out of the box and will not allow any power to get where it needs to go. If it is indeed bad, replace it and test your 4 Flat. You should be good to go, but if you...

• 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...
