I want to test a diode bridge with a multimeter or megger. I know if you test a single diode with a multimeter (ohm settings) then with your leads in one arrangement you will get continuity however if you reverse the leads the diode will block current and your meter will read open.
If I am testing a full diode bridge then if I connect my meter leads to the two input of the bridge then I will get current flowing through the bridge in one direction on half of the bridge and will read continuity. When I reverse my leads I should still see contunitly (the same as first arrangement) on my meter as current has reversed direction and is flowing through the bridge on the other half of the bridge. If I do not get continuity from one of these tests and get a high ohm reading then its safe to say that one of the diodes are bad.
Is it a good idea to disconnect the secondary circuit and just jumper the bridge's output terminals so that you are strictly testing only the brige and not the external circuit?
