Do trailer light converters go bad?
Unfortunately a trailer wiring converter module like # 118426 can go bad at any time without any notice. It is rare, but can happen. The module has a circuit board that will work great until it doesn’t and if that goes, it can do some odd things like what you are experiencing.
How do you test a trailer light converter?
What you will want to do is test the wires going into the box of the converter box for voltage with a circuit tester like the # 3808 to see if there is voltage going into the box when the taillight functions of your vehicle are applied, and then test the output side of the box to see if the current is making it through …
Do you need a taillight converter for a trailer?
Most trailers operate on a two wire system where the brake lights and turn signals operate on the same wire. When the towing vehicle has separate wires for brake lights and turn signals, a taillight converter is required. The converter you choose depends on the type of trailer you’ll be towing and the car or truck you’ll be towing it with.
Why are my trailer tail lights not working?
Trailer tail lights not working? Make sure that each of tail lights is properly grounded. Ground is achieved in one of two ways. In the first case, separate wires come out of each tail light assembly and are attached to a metal frame. A more common case scenario presupposes ground to be provided through the bolts of the tail light assembly.
Can a taillight converter module go bad after working?
If the module suddenly stopped working and there are no visible problems with connectors, it is possible that internal trailer wiring is the source of the problem. Trailer wiring can during normal use rub against internal metal surfaces and eventually lead to a short.
How do you attach a left turn taillight?
Using a circuit tester or volt ohm meter (VOM), determine which wire attached to the left taillight assembly is the left turn wire. Attach the units yellow left turn wire to this wire using a blue wire tap or Scotchlok. Determine which wire is the taillight circuit and attach the module’s brown taillight wire to it with a wire tap.
Why are my tail lights not working on my trailer?
If the pin on your vehicle side connector has a constant signal when your tail lights are on, then you know the problem is on the trailer. My first guess would be a poor ground connection somewhere. Be sure you check that the ground connections for the trailer connector and each tail light are mounted on a good clean ground location.
