Haven't tried yet, but hoping I can reproduce the overload with the trailer sitting. After stopping and sitting still I can pump the brakes all day long and no warning. Gonna take some work that's all there is to it. I'll share what I find....or hopefully find. Thanks for all the good tips.
Greg,
It may be that a shorting brake wire only comes in contact with a ground when the trailer is in motion and slowing due to brake deployment.
Rewiring the brake system is one of the easier wiring jobs on a trailer since nearly all of it is out in the open. You can get as obsessive as you deem fit with the process.
FWIW, I ran all the brake wiring into loom and flexible conduit since I have first hand experience with trailer wiring failures. All it takes is one small rock bouncing down the road or a wheel spitting a pebble at a wire, to part a wire. Sometimes, the wire breaks inside the jacket and is very hard to pinpoint.
