Testing installation for electric circuits of a motor vehicle
First Claim
1. A test installation for testing different load means of electric circuits of a motor vehicle comprising a control unit for receiving input signals and for producing test signals, said control unit including converter means for converting said input signals into output signals for switching said different load means and generator means (20) including interrupting means (36) for interrupting said input signals and for producing test signals independently of the input signals and at least similar to the output signals and for cyclically supplying said test signals to the load means when interrupting said input signals.

Abstract
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.
