WebSep 17, 2024 · This diode is the rectifier ahead of the 3V3 regulator: What happens is that the forward voltage drop across D1150 becomes so great that the input voltage to the 3V3 regulator falls below a critical voltage, below which the 3V3 regulator can not function properly. The faulty diode will pass a basic diode test with a DMM (as mine did). WebMay 8, 2024 · Most of modern multimeters have a diode test function. The test procedure is as follows: touch the anode with the red probe and the cathode with the black one. The working diode will light. If you change the probe polarity, the meter will display “1” and the diode won’t light. Neither will a faulty diode light during the test.
