Abstract:
A brake circuit that includes parallel electrical paths extending from the brake controller, through connectors, to the trailer brakes. The circuit having a primary circuit path extending from the power supply to a connector, through a diode to the brakes and back to the power supply and a secondary circuit extending from the power supply to a connector, through a diode to the brakes and a back to the power supply, and a pair of indicator lights connected to each circuit path between the connector and diode at one end and the power supply at the other end.
