People going out on frequent trips usually purchase large vehicles like motorhomes or RVs. This is because of all the features that come with these vehicles. Although, these can be too expensive for some users.
Considering this, one better option is to purchase trailers instead. These come with the same benefits however, if you already own a large vehicle then you can tow down the trailer to it. This way you will not have to pay for the extra cost of the engine and mechanical gear that move the vehicle.
Although, one thing that you should know about is that most trailers are required to put running lights on them. This is because of their large size, having the lights alert people that a vehicle is approaching or driving in front of them.
However, if your running lights with a 7-pin connector are not working on your trailer then you might be worried. This is why we will be using this article to provide you with some troubleshooting steps that should help in fixing this.
7 Pin Trailer Running Lights Not Working
- Clean Your Plug
When you notice that your running lights have stopped working. The first thing that should be checked is the 7-pin plug on your lights. This is because the plug is the main thing that connects all the lights and wirings to your trailer.
If there is any problem with it then that might be why your lights have stopped working. Another thing that you should note is that this 7-pin connector also controls all the indicators and tail lights on your vehicle as well.
Considering this, if you notice them flickering or not working then the connector might be the reason behind it. You can start by taking off this plug and then observing it.
In some cases, the issues can also simply be the plug getting loose or coming off. This is why make sure that the connection between the socket and plug was tight.
You can then clean off any dust that was collected on the pins of your plug. Some of these pins might even have corrosion between them which can stop electricity from passing through it.
If you notice this then make sure that you completely clear all of the corrosion. You can use either sandpaper to scrape this off or even use a cleaning agent that can remove corrosion. Using warm water can also help in taking all of this off.
- Check Pin Heads
The next thing that you can do is to check the pinheads on your plug. These should all have a small distance between them. Sometimes these heads can start to come together and get joined with each other. Considering this, carefully notice if any of the heads on your 7-pin are meeting with each other. If you do notice any then split them in the middle gently.
You can use any sharp thing like knives or screw diver to remove the contact between these again. This should help in tightening the connection again which is necessary. Make sure that you do not apply too much force as the pins can easily get damaged.
Aside from this, another important thing to keep in mind is that you do not move around the plug while it is connected. This can break any damaged pins or make them loose.
- Replace the Plug
Finally, if you have followed both the steps mentioned above but your running lights are still not working. Then there is a high chance that your plug has broken down. You can take it apart by removing the two screws holding it down.
Although, keep in mind that checking the wirings will be impossible for someone who does not have any knowledge about them. Additionally, this can be quite dangerous to do on your own.
Considering this, your best option will be to simply replace the plug completely. Additionally, when you were trying to remove the corrosion from your pins. You might have noticed that the pins have gotten thinner than before.
This is why it is a better option to get your plug replaced with a new one after some time. This way you will be ensured that your running lights do not stop working while you are on a trip.
