This is NOT the typical DC (+) output voltage waveform. One output diode is not functioning. Note the “gap” in the waveform. One output diode was disconnected to simulate an open or nonfunctioning output diode. Each vertical division represents 50 volts and each horizontal division repre- sents 5 milliseconds in time.

Note: Scope probes connected at machine output terminals.
