How do you test brakes on a trailer?
You can test the trailer brakes directly by disconnecting the trailer and applying 12V power to the appropriate pins on the 7-way plug; these are the pins that match up to the contacts on the truck’s trailer socket. You can use the truck’s battery or a spare 12V battery to apply this power directly to the trailer.
