I just had to have all new brakes put on my trailer at about 13K miles. 3 of the 4 were metal to metal. Usually run the controller 5/6. Has anyone heard of a brake test using a compass? It says with the brakeaway pin in (no voltage to electromagnets) put a compass up to the hubs. Compass should point north. Pull the pin and compass should point to the brakes. Well, With the pin in, I have 3 that the compass is pointing to the brakes! For the heck of it, I ordered a new breakaway switch. What else could possibly be an issue?
Based on your description three appear to work properly and one is not. I don't think the problem is the break away switch because three work. For some reason one magnet is not working. Either the magnet is bad or there is a bad connection in the wires.
The compass is just detecting the magnetic field created when the breaks are applied. Sometimes a hum can be heard from the magnets.
