The Trailer Tester is designed to help you quickly identify problems in the wiring of the trailer. This is done by testing the Left Turn, Right Turn, Tail/Marker, Brake and Back Up circuits on the trailer. The tester indicates the approximate amount of current in each circuit. It will also test the voltage of the external battery connected to the trailer charge circuit (i.e. trailer battery).
