Sonny sounds like u need to pull that trailer into the barn and leave it till spring! I used to have to rewire trailers on a yearly basis, seems like SOMETHING always goes bad..did an upgrade to LED lights and half the issues went away..I used to build trailers, very handy to have..now I hate working on them with a passion..and I damn sure dont loan 'em out..done with that..I have plenty of cold weather shop jobs to do right now, burning that fuel oil at 5.50/gal..sure feels good to walk into a warm shop in the mornin..vehicles and trailers can wait till spring!
