ABSTRACT:
Starter device comprising an electric starter motor and a main switch of the normally open type connected between a supply input of the electric motor and a battery. The device comprises a main switch activation circuit comprising a first and a second switches arranged in series with each other and connected between the battery and a main switch activation device. The first switch is in the form of a manually operated switch operated by an ignition key and the second switch, of the normally open type, is closed by a power enable signal output by an electronic control circuit designed to inhibit the production of the enable signal when the voltage of the battery falls below a threshold value. An electrical connection device extends between the supply input of the main switch and a control input of the second switch in order to provide a supply voltage to the control input and keep the second switch closed independently of the production of the enable signal.
