Help with trailer brakes
Actually, my brakes work fine (on a car hauler trailer). Really. But my 2012 Ford F350 systems monitor is not seeing what it needs when the trailer is hooked up and issues continuous inappropriate...

When measuring the resistance of electric trailer bakes at the trailer end plug, you should get 4 divided by the number of wheels. I got 1.0 – 1.1 on my two axle trailer.
Since I only have two brakes that would mean my resistance should be 2 ohms. So I disconnected my brake leads from the wires, and substituted a 2 ohm power resistor. Checked that the terminals at the 7-way measured 2 ohms -- they did. Plugged into the truck and the truck tells me "trailer disconnected". Didn't fool it.
But I'm convinced I have flakey magnets. I rechecked the resistance right at the magnet leads. They have excessive resistance yet work on the road. My empty trailer locks the wheels where it's supposed to. I give up. I'll just replace the magnets and see where that puts me.
