First adjust the trailer brakes and try again.
If you need an excuse to get a DC clamp-on ammeter this is it. Apply the trailer brakes manually and see if you get about 3 amps to each wheel.
Less than 3 amps you need to trace the wire for an open connection.
3 amps and the electrical is good so you need to pull the drums and inspect the mechanical parts.
More than 3 amps is probably a short inside the drum.
