Thanks

Make sure that the trailer doesn't have anything grounding out with the running lights and that the actual ground for the wiring has good contact. I had the same problem with mine. It worked fine on my dad's H3 but it kept blowing the fuse on my H2. I checked all the lights and found one that had a wire touching the metal. Then I took off the ground on the harness and scraped off the paint where it connected to the frame and put it back. It works like a champ now. Good luck!
