TROUBLESHOOTING TRAILER WIRING ISSUES

 You are doing a daily checking on your truck before going on the roadway and you observe some of your lights are not working. Do you go to the trailer repair shop near me for a wiring fix? No, the initial step is to troubleshoot the wiring of the trailer. Wiring problems are generally simple to resolve and fall under one of the following kinds.

DOES THE ISSUE LIE WITH THE TOW VEHICLE OR THE TRAILER? 

Disconnect the trailer from the towing vehicle. Test each of them individually. For the testing, you could utilize either a jump starter pack or a standalone vehicle battery. 

FAULTY GROUND CONNECTIONS: 

Weak or bad ground connections are the most common cause of wiring issues. Clear all connections to remove existing corrosion or paint build-up. Clean unless you accomplish clean metal.

If your ground screw is full with other portals, move it to another place or towards the bottom. Another thing you can do is to reconnect the ground wire to a wire that is connected to the negative portal of the vehicle. For the trailer, make sure that the ground wire connects to the frame of the trailer. 

On the other hand, if the ground screw or ground wire is thoroughly corroded, change it. 

CHECK FUSES AND OVERWEIGHT CONNECTIONS:

Test the fuses in both the trailer and the towing vehicle to decide where the fuse issue could be. If a blown-out fuse is a recurring issue, then your lights are overweighing the circuit. 

Check the maximum amperage ratio of the harness, and compare it to the power your trailer lights draw. If your harness works without any lights, but shorts when every bulb is present, there is overdraw. Change your clearance lights with LED bulbs, with their low consumption of electricity; they would rapidly solve the overweight problem. 

CONFIRM WIRE CONNECTIONS AND TERMINALS: 

The other common wiring issue is creased loose, or non-sealed connections. Only crease connections are often loose even when they feel tight. It would save you ample energy to change all the crease-only connections to crease and solder connections which are safer. Check for loose connections or wires that are attached incorrectly. 

You could as well do a continuity test to check for broken wires. Choose one color wire in the socket and trace the similar color wire in the connector front. Clip one end of this wire to the connector pin and the other end of the continuity tester. If the trailer lights are sifted, follow the wire, cut off any faulty bits, and solder new wire on. Repeat with the other color wires. 

Keep in mind to check if the bulbs have gone out and replace them as required by screwing them off from then on. 

Corrosion and paint build-up could as well interfere with the function of the wiring of your trailers. Ensure any aluminum areas are clear of paint and all corrosion has been cleaned off using electric contact cleaner and fine sandpaper.
