Abstract

Official abstract text for this publication.

A diagnostic circuit for trouble shooting electronic control units of appliances includes a voltage sensing and signal generation device with an input/output and an input. The circuit includes first terminals for connecting to the load and second terminals for connecting to the two lines of the sinusoidal source. One of the first terminals is connected to the input/output, and another one of the first terminals is connected to the input. A relay is connected between one of the second terminals and the input/output. Another relay is connected between another one of the second terminals and the input. A first diode pair with clamping diodes is connected to the input/output, and a second diode pair first diode pair with clamping diodes is connected to the input.
