Horse trailer I bought used awhile ago, just getting around to hooking up brakes. Controller and breakaway battery both deliver voltage to wires under trailer, so I pulled one of the wheels. The magnet has voltage to it, but there's no magnetic field that I can detect. How strong should the field be? I'm thinking it has to be pretty strong or this mechanism isn't going to work. The brake actuator is free and the shoes seem to move fine. I also don't hear any clicking noise on the other wheels when I apply the voltage. I don't believe all 4 magnets could be bad at once. Is it possible I'm getting a good voltage level but not enough current? I installed a new ground and fixed the old one, so there's two good quality grounds on bare metal. All electric lights work properly. Thanks for any suggestions, brakeless in Chicago...
