How do you test electric brakes on a trailer?
You can indeed test a trailer’s electric drum brakes by directly applying +12V power from a fully-charged battery. You can apply this power to the hot and ground contacts on the trailer’s plug (see photo please) or to an individual brake assembly’s two wires.
How do I know if my electric trailer brakes are bad?
Testing Individual Brake Magnets Check the amperage. If the amperage is greater than the specified amount (see specifications below), replace the magnet. If the reading is less than the specified amount, the leads are bad and the magnet should be replaced.
How to troubleshoot an electric trailer brake problem?

Do you think trailer brakes actuate by controller?
So I’m guessing my theory was correct: the old, mostly broken ground wire was a good enough ground to operate all the trailer lights. But it wasn’t enough to support the significantly heavier electical load required by the brakes. Was this answer helpful? I think you had a bad ground.
