And if so, how to I get them working again? Thanks.
if the umbilical was disconnected and the brakes stayed applied, the battery wasn't dead.
if the breakaway switch is working properly, the reconnected brakes should be ok, provided that it wasn't long enough to ruin the brake magnets.
polarity does not matter with the wires at the wheels. i'd try testing with just one wheel rewired.
you can do some testing with just the trailer if the battery is ok now. put a jumper wire from the 12v
hot to the brake wire at the umbilical end.
