Generator Rectified Voltage Waveform
I – generator is OK;
II – diode is broken;
III – open circuit in the diode circuit
The oscilloscope allows you to accurately and quickly check the generator's serviceability and determine the nature of the damage based on the shape of the rectified voltage curve.
1. To check, connect an ammeter, rheostat, switch and battery to the generator terminal "30", as shown in Fig.
