Abstract
The invention relates to a method of supplying power to a motor-vehicle electric-starter contactor (10) in which, on a circuit (T1, B, 20, 25) for supplying power to the contactor (10), an effective-power-supply signal (R1, R2, R3) is provided having a chosen profile, characterised in that, on the power-supply circuit (T1, B, 20, 25), a supplementary signal (T, R4) is also provided having a shape which is chosen in order to facilitate the identification of the profile of the effective-power-supply signal (R1, R2, R3).
