Trailer Lighting

[Scott Forman]

Last night, I plugged a borrowed trailer into my bus. The tail and
turn lights worked fine, but whenever I would step on the brake, the
circuit breaker for the brake lights circuit would trip after a second
or so. I also had a reading of +50 amps on the ammeter, which went
away the moment I unplugged the trailer.

The trailer has LED lights and did not cause any trouble behind my
truck. It does not have trailer brakes.

I suspect I have a problem in my trailer socket. Anyone have a
suggestion of where to start looking?
