Trailers usually come with a cable connector 4 or 5 flat or round, seven-wire connector. If your trailer has an electric wire connector that does NOT mean that your trailer electric brakes. The electrical brakes are a separate connection.
The purpose of the wiring connection is to match the action of light in the tow vehicle for trailer lights. This includes the running (night) lights, emergency flashers, turn signals and brake lights. A connector four wire contains a ground wire (connected to the chassis of the trailer), running light wire (goes to the two trailer lights left and right) and turn signal / brake light lead lights for left and right.
If you have a cable connector of five years, the cable is used for the fifth one solenoid a hydraulic actuator used to stop the brake when backing up. These are commonly called a "backup solenoid", "the solenoid reverse flow "or" flow stop solenoid. "fifth cable tow vehicle is connected to the reversing lights of the towing vehicle. This activates the solenoid when the vehicle is placed in reverse.
Most of the problems of the trailer lights are derived from a bad connection land between the tow vehicle and trailer. Since there is no ground wire going back to each light (very few trailer manufacturers add additional grounding wires) the proper ground for each light depends on the land of the towing vehicle wiring and grounding in all aspects.
Indicators that you have a bad ground are:
- Weak or trailer lights dim
- Facing the light attenuation when the signal turn is
- Running lights are off when the turn signal is on
- All lights are off and flashes when the signal slightly turn is
Check the simple things first if all the lights act strangely.
- Check wiring connector between the tow vehicle and trailer. Clean the connectors exposed with a fine sandpaper or steel wool. Have the cables have not been reduced or eliminated on the pavement.
- Check the ground wire connector of the trailer. This cable can not be fitted under the edge of coupling. The cable has to be against bare metal clean, with a screw or bolt to the structure. Preferably a separate hole drilled in the framework of this connection.
- If only a light acts verify that the first light bulb for proper connection, carefully remove the bulb and clean the connectors on the back of the bulb and the inside cover of the light. Check field for the frame. This may be a short cable of just the screws holding the light to the trailer frame.
- If you have a bell wire or similar long, can check the soil to each lamp. Place a clamp on each end of a cable that is long enough to go from the trailer until the end of the trailer. Connect one end cable to the chassis of the vehicle, make sure you get a good connection to bare metal. Connect the other end to the land of light. Compare the results. If the light works best which is the most likely place where the ground is bad.
- If the lights blink quickly and not a full brightness, you might need a new flashing light in the trailer. Check with your local auto parts store to replace the existing flasher with a high definition model.
Remember that the trailer lights to tell the traffic around you what you are doing. Incorrectly work lights are a danger to you and all around driving.
