• Trailer Lights Malfunctioning behind a GMC Truck with a Factory 7-Way and a 7 to 4-Way Adapter
  
• If the 7-Way blade socket on your GMC is factory, then the brake and turn signals are combined. There are a few possible sources that come to mind. It could be some problem with the wiring on the trailer, a bad ground somewhere, the adapter may be mis-wired internally or if it has been exposed to moisture, it may be corroded inside and causing faulty connections. I am not sure how brake lights would cause the trailer lights to go on and also turn all lights off. Use a circuit tester like p

• Troubleshooting Right Trailer Brake Light Not Functioning but All Other Lights Work
  
• This sounds like a ground problem. A loose, broken, or corroded ground connection can cause all sorts of unwanted performance for electric components including trailer taillights. I would start with checking for a proper ground at the taillight itself. Many times, trailer taillights ground through the mounting studs. Check for any corrosion and give them a good cleaning to get the best connection. You will also want to check the ground at the front of the trailer for any dirt or corrosion. Fi

• Trailer Connector On 2009 Dodge Ram 2500 Is Not Working When Connecting Gooseneck Travalong Trailer
  
• It sounds like the vehicle end connector in the bed of your truck is damaged or the wiring in the trailer connector may be damaged. Using a circuit tester like the Quickee Circuit Tester, # 3808, you will want to test the wires going into the 7-way on your 2009 Dodge Ram 2500 to see if the connector is damaged. If the wires show current to the connector but the connector is not working you need to replace the vehicle connector. If they do not show current the problem will be further up the wirin

• Malfunction of Trailer Blinker Lights When Lights On Truck Are On
  
• It sounds like there may be a loose or bad ground on the trailer light. When the lights on your truck and trailer are on and you use the brakes or turn signal, the system is at its max load of amps and with a bad or weak ground, the light cannot support all the power of both the running lights and turn signal. I would start by checking the ground connection on both lights to make sure there is contact to a clean, rust-free metal surface. Also, if you have a plastic license plate holder, this

• No Taillights On Boat Trailer When Connected To A 2003 GMC Yukon XL 7-Way Connector
  
• It sounds like a blown tow package fuse in your fuse block on your 2003 GMC Yukon XL. You will need to check the accessory fuse block under the hood of your vehicle. When you remove the cover of the fuse block there will be a legend on the underside of the cover that will show the location of the fuse. If the fuse is blown you will then want to check the taillight wiring on your boat trailer for any pinched or frayed wires that could be shorting out on the trailer frame and causing the fuse

• Troubleshooting Ground Wire attachment on a Trailer for the Sealed Oval Trailer Lights # ST70RB
  
• If your inclination is that you are having ground issues then you most likely do. Ground problems are the most common problem with trailer wiring. I would recommend grounding the white wire on the 3-Wire Pigtail, item # A45PB, to the trailer frame. If the mounting location for the # ST70RB Oval Trailer Stop, Turn and Tail Light, is not welded to the trailer frame I would recommend attaching the white wire directly to the trailer frame rather than a bolted or riveted on mounting bracket.

• What is the Approximate Amperage Draw of the ST70RB Sealed Oval Trailer Light
  
• The Sealed Oval Trailer Stop, Turn and Tail Light, item # ST70RB, uses an 1157 automotive style bulb with two filaments. The bright filament is rated at 21 watts and the dim filament is rated at 5 to 6 watts. With the filament wattage, we can determine the amp draw of the bulb. Amperage equals watt rating divided by input voltage. Assuming a 12.8 volts input in all cases, with both filaments lit, the amperage draw would be approximately 2.1 amps. With only the dim filament lit, the amp draw w

• Troubleshooting Left Side Stop and Turn Signal Light Not Working on a Flatbed Trailer
  
• My first reaction is a weak ground connection for the left side light. If the left turn and brake signal are on a separate circuit but a ground connection that is not sufficient, a number of things can go wrong, including one of the lights functions not working, while testing shows 12 volts power. I had this same issue on a utility trailer some time ago also, and it ended up being a frayed wire that was just barely making contact to the trailer frame. In my case the issue was intermittent and

• Trailer Lights Not Working After Cleaning Grounds and Making Fresh Wiring Connections
  
• Do not despair. I will be happy to help. This does sound like a classic ground issue but there could be some other factors involved as well. So we will start with the easy things to check and work our way from there. Testing the trailer connector on the truck was a good start. The next thing you will want to do is plug in the adapter to the 7-Way and test the pins on it. If they are incorrect, there could be a problem with the adapter. Next, you can plug in the trailer and test the wires comi

• Load Resistor Recommendation for Use with LED Tail Lights on a Flat Bed Truck with Hyperflash
  
• You will wire a load resistor into the wiring of each light socket that has an LED bulb and flashes. So basically you will need to wire a load resistor into any bulb that blinks or has a dual intensity feature that lights up when the brakes, blinkers, or emergency flashers are operated. To do this correctly, you will need to wire the load resistor on the positive wire and then either ground it to the ground wire of the bulb, or to a good frame ground. You will need to do this for all of the L
