Re: Help Please!!
Yes, your way can work without a doubt. I have worked on many trailers (boat, RV. ATV, and utility). I've only had problems from those that used the trailer as a ground, never with those wired directly to the vehicle (other then blowing a fuse). The best grounding will be one that is connected to the source. Then there are builders that insulate the engine from the frame (rubber/tape/cut up tubes, etc), and paint can cause a insulator effect. Wiring through the frame can work, wired to the source will work,
