ABSTRACT:
Testing of inductive devices for the presence of voltage suppressors in circuit with said devices. A voltage responsive indicating element is combined with a circuit for applying a pulsating voltage to an inductive device. The indicating element senses the amplitude of the inductive voltage spike produced by removal of power from the inductive device to thereby indicate the presence or absence of a voltage suppressor.
