I just replace all my dump trailer brakes and bearings. Chasing an issue where it wasn't helping out my truck much stopping. Pounded out all the old races, packed inner and outer bearings...covered head to foot in grease. Wired up the new brakes... electric... passenger side was dead. Driver side is connected directly to a j box that goes to the pigtail to the vehicle... passenger side has a wire that runs through the hollow axle tube... checked continuity on BOTH axles and BOTH pairs of wires had zero conductivity. But I was able to use them as fish tape to get the bad ones out...so zero physical break in the wire or insulation. Both wire pairs were soaking wet...so I drilled holes in the bottom passenger and driver side of both axles...they crown in the center...and drained out a lot of water.
Point of this story is it's probably the wiring and it probably visually looks great...but like my dump trailer it just didn't work any longer.

P.S. remind me not to go mudding with my dump trailer.
