Abstract
A control system of the type which provides 'breakaway' safety action to energize the electrically actuatable coils of brakes in a trailer pulled by a towing vehicle, the coils being energized under a breakaway condition from an auxiliary battery carried in the trailer. The present system is characterized by a voltage threshold indicator which is connected across the auxiliary battery and the coils and which enables the driver to test the auxiliary battery and clearly determine if the battery has sufficient storage capacity to keep the coils adequately energized while load current is being drawn from the battery and supplied to the actual coils themselves. The indicator preferably is incorporated in a pull-apart breakaway switch unit which automatically connects the brake coils with the auxiliary battery in the event of a breakaway.
