ABSTRACT:
An anti-skid control circuit for a wheeled vehicle has a connector (15) for connection to external circuits and a warning circuit contained within the control circuit and connector (15) for enabling a visual indicator (17) upon the occurrence of a loss of power to the anti-skid control circuit, a malfunction of the anti-skid control circuit, or disconnection of the connector (15) from the anti-skid control circuit. The anti-skid braking system warning circuit includes an electrically energizable the visual indicator (17) in the form of a lamp (17), and a first transistor (33) connected in series with a source of electrical energy. A control transistor (35) is conductive to shunt the base-emitter circuit of the first transistor (33) so long as the anti-skid braking system functions properly. When the control transistor (35) becomes nonconductive indicating a lack of the anti-skid function, the base-emitter circuit of the first transistor (33) is forward biased and the lamp (17) energizes. A two-part multiconductor (25, 31) of the connector (15) electrically connects the visual warning indicator (17) and the first transistor (33). The connector (15) includes a circuit for connecting directly the lamp (17) to the source of electrical energy whenever the multiconductors (25, 31) are separated.
