Security installation

A testing installation for electric circuits of a motor vehicle, in which input signals are converted in a common central control unit into output signals for switching different loads; the testing installation includes a generator which produces signals at least similar to the output signals of the control unit and feeds the same cyclically to the loads or the switches thereof; as a result, only the critical portion of the electric circuits is switched and the functioning ability thereof is tested optically or acoustically without further auxiliary means.
