Chattering trailer brakes
Been towing for years, but first time I've run into this. When applying TV brakes, the TT brakes chatter when coming to a stop. Essentially they are quickly applying, letting loose, applying, etc....

Typically the wires to the brakes go through grommets into the axles to run from one side to the other. I've seen these wire's insulation chafe and short to the axle tube. While your wires to the baking plates look good, have you inspected the wires IN the axle? It could be the insulation is worn through beyond where you can visually inspect inside the axle tube. Is the trailer chassis ground good and not intermittent? Good luck.
