A method for detecting a faulty connection of an auxiliary battery (6) incorporated in an auxiliary network (5) of a motor vehicle supplied by the auxiliary battery and by a non-reversible current source (4), such as a DC/DC voltage converter or an alternator, which is voltage controlled to supply an output voltage which is a function of the setpoint voltages. The detection method includes determining at least one minimum and/or maximum voltage value which cannot be reached by the voltage at the terminals of the auxiliary battery (6), then assigning the function of setpoint value to the minimum and/or maximum voltage value, controlling the current source (4) by sending the setpoint value to it, measuring the voltage at the terminals of the auxiliary network (5), and deducing a faulty connection of the auxiliary battery (6) if there is a match between the measured voltage and the setpoint voltage.
