@dman535, if you know how to pull off the drums you can fix this. Yes, the dealer *should* fix this under warranty, but in my view I would rather fix it myself than put my camping season on hold waiting for a dealer appt. BTW, you're only "voiding the warranty" on this issue, not the whole trailer.
Even if you replaced all of the wiring between the tongue and the brakes, it's not that big of a job. You can get some good quality marine duplex wire at good prices here at
Best Boat Wire. Just run new wire and zip tie to the outside of the back of the axle...get some waterproof crimp connectors to attach to the brake magnet leads. Some folks have upgraded the wire to #12 to minimize voltage drop and improve brake performance.
You may never find the problem but at least the brakes will be fixed and the camping can resume!
