3 Solutions for Common Trailer Wiring Issues

trailer wiring

When it comes to trailer maintenance, most people like to focus on the mechanics and the actual structure of a trailer, which is comprehensible knowing that if those two aren’t in good condition the trailer will simply not work and it will not be possible to use it. That’s why often the trailer’s wiring and lights may be overlooked. However this area is just as important as the general performance of the trailer since it plays a key safety role. Without lights, how are you going to alert pedestrians and other drivers of your movements?

With this being said, there are some issues that can come up with trailer wiring that every  owner should be aware of in order to fix them. Today we will show you 3 easy solutions for common trailer wiring issues.

3 easy fixes for common trailer wiring issues

Inspect ground connections

Checking the ground system is one of the basics, since a ground light fixture wire provides security, avoids the possibility of an electric shock and ensures safety in the situation of a wiring circuit malfunction. The ground wire should be connected to the frame of the trailer and the ground region should be often inspected for corrosion and paint build up. This area should be cleaned until a clean metal surface is reached or the corroded ground screws can be replaced.

A way to test the connection: disconnect the ground wire and attach it to a piece of wire that runs on the main vehicle’s negative battery terminal; if it solves the light wiring issue it should be kept in place, if not it should be replaced.

Look for overload conditions

Overloads are caused when circuits work with more electricity than they can handle, which causes overheating and wire melting. That is why it’s key to be aware of the maximum amperage rating of the wiring harness connected to the trailer and compare it to the draw of the lights installed. If the lights on the trailer draw more amperage than the harness can handle there is a simple solution, remove the bulbs from the extra clearance lights, try to connect the trailer again and see if the harness works without these. If it does, this indicates an excess number of lights. You can always replace them with LED versions to draw less power.

Check for corrosion

Corrosion is easy to find since it looks green or white and should be checked for after seeing that the the car’s lights work and the trailer’s lights seem dim or aren’t working. When corrosion reaches wiring sockets it causes the lights to not work and the plugs connected to it should be either replaced or cleaned. A way of fighting corrosion is spraying the connector with electrical contact cleaner and brushing the contacts with a fine wire brush. This should help create a stronger connection between the wires. An alternative method involves using 220-grit sandpaper to clean wires and connections.

Taking care of trailer wiring is a must do before putting it to work, and as you can see from these tips, doing it isn’t that difficult. Follow these and any minor wiring issue should disappear.
