Leaky Diode | Electronics Repair And Technology News· So, i retest again with my analog meter (set to X1 Ohm) to see if there is any erratic movement in the pointer. At first glance, you thought the output diode was good, but when i applied a little bit pressure on the diode with the help of the probes while still testing the diode, i saw that the pointer have erratic movement. That was the cause ...
