For most buyers, trailer wiring fix could be an annoying event. Diagnosing the basis on the difficulty early in the process is the important thing. I will suggest a 12 volt stick-tester to test your own wiring and connect for continuity as first faltering step in almost any electric repairs. Plug testers are offered for all types of trailer plugs, but a stick tester can be used on any receptacle and will test wiring between contacts. And they usually cost a lower amount than ten bucks.
Very first, because of the truck wiring attached to your tow car, turn on your own operating lighting. I recommend doing this making use of the hitch maybe not attached to the trailer coupler, for causes we’re going to explain after. Create a walk round the trailer and check to see if all lighting were illuminated. If the pull car blows a fuse in this level, first eliminate your own trailer tail-light lenses and check for blown bulbs (usually black or creamy white inside if blown), plus test to be sure the bulb is within correctly.
