Can you just try a different brake controller and see if that recognizes the trailer?

It will if you grounded one light bulb, fan ect, to the chassis.

I have..... and I hope I'm doing it correctly, the testing. On each brake magnet I don't get any reading at all. My meter shows "0.0".
If I touch the probes together (one on the other) I get a reading of .5, sometimes .6, just to see what the resistance in the probe's wiring is.
So I'm thinking the windings in both magnet's coils are open (broken). I'm not sure why or how that came about .... if in fact that's the issue. I have an appointment with a trailer shop on Thursday to get another set of eyes on the problem.
