• Troubleshooting Roadmaster Invisibrake System Pulsing with Flashers 5 Times and Stopping
• Yes. This is the normal occurrence when using the flashers in conjunction with your Roadmaster InvisiBrake Supplemental Braking System # RM-8700. Once the system goes through this sequence your vehicle's lights and brakes will work correctly. I confirmed this information with my contact over at Roadmaster and this is how the system was designed.

• Troubleshooting Intermittent Function of Blue Ox Bulb and Socket BX8869 Installed in Vehicle
• Sounds like maybe an intermittent connection on the ground circuit of the trailer wiring on the motorhome. Try cleaning the pins of the trailer connector to see if that improves the connection/ground and allows the kit to work.

• Troubleshooting Bargman Triple Tail Light With LEDs And Incandescent Bulb
• The Bargman Triple Taillight, part # 47-84-005 features a Red and an Amber LED light, but the reverse light is incandescent. This is a 3-wire light. The red LED funtion is the red taillight. The Amber LED is for the turn signal, and the incandescent light is for the reverse light and is surrounded by a red reflective lens. You may have a wire connected incorrectly and that can be fixed pretty easily. Just use a circuit tester like part # PTW2993 and attach the wire for the incandescent...

• Troubleshooting Brake buddy on Jeep Wrangler Unlimited
• If you are of the impression that a faulty signal is being sent from your Brake Buddy, # HM39524, I suggest you remove all power for no less than 15 minutes allowing the unit to reset. We want to ensure you do not have any vacuum pressure built. If on resuming testing you have a repeated error in operation check the signal from your breakaway switch, ensure switch is fully seated. From the Tech Rep at the manufacturer, they also suggest that you double check wiring at switch housing...

• Troubleshooting Roadmaster Smart Diode Kit Install Where Lights are Dim and Hyperflash
• It sounds like there is some wiring issues going on with the diodes of the Roadmaster Smart Diode Kit part # RM47ZR or your Wrangler does not have the ParkSense feature. This is designed to convert the 12 volt signal from your RV to the 9 volt power that your 2022 Jeep Wrangler Unlimited uses for it's taillight circuits so since you are seeing dim voltage which is usually associated with lower voltage than required to operate a light and hyperflashing my first thought is that something...

• Troubleshooting Brake Light Issues With A Hopkins Custom Tail Light Wiring Kit
• For your # HM56200 the first thing to check is to make sure everything is grounded. 1. The connector on the vehicle should have a ground wire secured tightly to a clean surface on the frame. A wire attached to the body or a surface with undercoating or rust can cause a ground problem. 2. The connector on the trailer should have a wire from the connector secured tightly to a clean surface on the trailer. 3. Each tail lamp assembly at the back of the trailer also must be grounded. This...

• Troubleshooting Roadmaster InvisiBrake Pulsing When Flashers Are Turned On
• This is definitely something that Roadmaster has seen occur with the Invisibrake # RM-8700, so there's nothing to fear. What you're experiencing should stop after a few cycles through with the hazards flashing and once the system learns that this isn't the brake signal it shouldn't happen again.

• Invisibrake Activates on Jeep When Started But Not Connected to Motorhome
• I discussed your issue with both my in-house installers and technical support at Roadmaster and they both came up with the same concerns. It is likely moisture and/or corrosion at the multi-pin connector at the front of your Jeep. I have attached a picture of a typical connector and would like you to note that it has a plate that attaches with 2 screws and a rubber boot behind it. If you take off the screws and pull it out, then pull the boot back you will expose the area where the individual...

• Troubleshooting Brake Lights Overriding Turn Signals On 2021 Jeep Wrangler Being Flat-Towed
• The Roadmaster Stop Light Switch Kit # RM-751490 is what is required for your 2021 Jeep Wrangler Unlimited, and not the # RM-88400 you mentioned. This is due to the stop light switch on your Jeep timing out of after so long. This kit is designed to stop the brake lights from overriding the turn signals, so since you are having these issues still that leads me to believe there is a wiring issue with either the switch or the tow bar wiring # RM-154. I recommend following the included instruction...

• Can Curt Echo Brake Controller Work with 5-Way on Boat Trailer
• In order for the Curt Echo Wireless Trailer Brake Controller # C51180 to work properly you will need to install a 7-Way connector on your boat trailer. Typically the 5-Way connectors carry the standard trailer light functions plus the reverse light function so I'm not even sure if your current setup is able to provide power to brakes on your boat trailer. I recommend using the Trailer Wiring 7-Way Upgrade Kit # HS381-9000 to accomplish this since it comes with a junction box that helps...

• Troubleshooting Non-Functional Running Lights on Toad When Using Hopkins Dingy Wiring
• When trailer or toad wiring has an issue with running/tail lights but other functions work fine the problem is most often related to a weak ground. What happens is that if a ground connection is not 100-percent solid and with bare-metal-to-bare-metal contact the weak ground will allow some lower-power signals to pass (stop and turn lights that don't draw as much current) but won't let the higher-current always-on taillights function. This is a common issue and it usually has a simple fix. Find...

• Troubleshooting Even Brake Portable Proportional Braking System On 2015 Jeep Wrangler Unlimited
• I called my contact at Roadmaster about the # RM-9400 and the troubleshooting message you keep getting. They told me that you need to check the green wire that is coming out of the # RM-751452 switch. You should only show current when the brake pedal is depressed. If you are not showing current, then the switch is probably bad or it has shorted out and needs to be replaced.

• 2005 Jeep Wrangler Left Brake Light Stays On All the Time When Connected to RV
• To determine where the problem is I recommend having the 2005 Jeep Wrangler Unlimited plugged up to the RV and then use a circuit tester such as # PTW2993 to test the wiring starting at the RV. You are looking for constant power on the left brake light/turn signal wire. Start at the RV and work your way back until you find the problem. If it doesn't show up until after the diode, then that could mean that the diode is the problem. Also, if you are using a supplemental braking system...

• No Left Turn Signal And Hot Yellow Wire On Curt Trailer Wiring For A 2019 Jeep Wrangler Unlimited
• Installing the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector Item # C56407 on a 2019 Jeep JL Wrangler Unlimited should be straight forward. Due to the plug and play connectors, typically there are very few things that could go wrong. To narrow down the issue you are having, I would start by removing your left tail light. Check the pins on each of the plugs to make sure none are bent. If any are carefully straighten them. Reconnect the plugs and make sure it...

• Troubleshooting Both Turn Signals Running At The Same Time
• The first thing to check is the connection pins on your wiring harness. Make sure there isn't any loose or bent pins or any debris. You can use some Dielectric Grease # 11755 to ensure a clean and proper connection. The second thing to check is your ground. Make sure the main trailer connector ground and the grounds for each of the lights are all connected to clean and corrosion free bare metal surfaces. The third thing to check is if you have any shorts in the wiring on both the motorhome...

• Troubleshooting Brake Controller Error Codes On 2012 Jeep Wrangler Unlimited
• It sounds like you have a short in the blue brake wire somewhere between the brake controller and the 7-way connector at the rear of your Jeep, especially since you said the error codes show up with no trailer connected. You will want to cut the blue wire about 4 or 5 inches behind the brake controller and see if the flashing SH code stops. If it does, then there is a problem with that wire, and you will need to check it all the way back to the 7-way. If the code stops flashing on the...

• Troubleshooting Left Stop/Turn Light Not Functioning On Trailer
• Sounds like you are trying to figure out why the left brake light on your trailer isn't functioning but the rest of the trailer lighting seems to be working. Typically this problem is due to a bad ground on the light assembly. The light grounds should be attached to clean and corrosion free bare metal surfaces. If there is anything between a light ground and the metal trailer frame or if the trailer has an aluminum frame, tilt bed, or folding tongue, any of these things can interrupt...

• Reverse Lights Stay On After Installing Mopar Trailer Wiring Harness on 2012 Jeep Wrangler Unlimited
• It sounds like the center post on your 7-Way is set up for auxiliary 12 volt power rather than reverse lights on your 2012 Jeep Wrangler Unlimited. You can remove the wire to the center terminal on the 7-Way and splice it into a reverse light wire behind one of the tail lights. Is this happening on a trailer you are towing or the Jeep itself? If it is on the Jeep then it sounds like there is a short that is jumping from the 12 volt circuit to the reverse light circuit and backfeeding somehow...

• What Does Clicking Circuit Breaker of 7-Way Install Kit # ETBC7 Mean
• If a circuit breaker is clicking that means it's cutting the circuit and doing it's job to protect the wiring and from passing the short further up the circuit. You said it's "not" clicking which would mean it's seemingly just fine but since there's a chance you meant to type "now" that would indicate that the circuit is overdrawing and tripping the breaker. This is most of the time caused by a short on the circuit's wiring but could also just be from overdrawing the circuit. If it's happening...
