Testing Bridge Rectifier

                   Set your analogue meter to X 10 K Ohms and place your meter probes to
                   + and ~ ac pin. It doesn’t matter which probes to which pin but as long as
                   it won’t show two similar low resistance reading registered by your meter
                   when you reverse the probes, it is okay. It should have only one reading.
                   Next, again place your probes to the + and to another ~ AC pin (there are
                   two “~” AC symbol in bridge rectifier) and should have only one reading
                   even though you had reversed the probes.

                   Similarly when you want to test the – (negative) with the first ~ AC and
                   then – (negative) with the other ~ AC. Look at the photos and you should
                   understand it. Assuming when you found one of the diode shorted in the
                   bridge rectifier, you have to replace the whole package. Replace it with
                   the same or higher voltage and ampere rating!
