Shorted Diode Test

By on September 12, 2007

The best to test a diode is to remove one lead from the electronic board. Set your analog meter to X 10 k ohms and place it on the diode either way. A good diode should show only one reading but a shorted diode will have two readings. Schottky diodes would have two readings but not shorted reading. So beware as to what types of diodes you are checking. Replace the shorted diode with the spec of same or higher than the original one. Find out the spec form the internet or from your favorite semiconductor data book.
