Re: trailer light problems , need help!!!!!
I think the best way is to do as Tasha says, run a seperate ground wire to each light fixture. Back in the 70s I had a fiberglass dune buggy on a VW frame, and I always had light problems with it, until I realized that my grounds were not good and once I fixed that up no more problems. With the 'glass body you had 2x the normal # of wires since each light had to have a seperate ground, and sometimes just running it to the frame doesn't work because of corrosion, so I ran seperate wires back to where the battery grounded to the frame.<br />Now if you don't want to do that much work, snaking wires and such, you could do it this way: make sure the white wire from the trailer harness is attached firmly to the tougue. Then run 2 white wires from the tongue to the frame side rails. Next, run a white wire from the end of each side rail to the rear crossmember where the stop, turn, brake and clearance lights are. That way if there is corrosion in the bolts holding the sections of the trailer frame together, it will not interrupt the ground path.
