A method for testing electronic automotive components. Apparatus required is an electrical device which includes a pair of probes, a source of direct current, and a bifunctional current detector. The current detector includes a buzzer and an incandescent lamp. The positive terminal is connected to the current detector, and the negative terminal to one of the probes. The current detector is connected to the other probe. The probes are then placed in contact with the component being tested, and an observation is made as to whether or not a current is detected by the current detector. The detection or failure to detect a current provides a signal indicative of the condition of the component tested.
