book such the famous Philips ECG master semiconductor replacement
                   guide. The data book will list out the general specification of the SCR
                   such as the volt and ampere. You may go to google.com search engine
                   and key in the part number and get the SCR specification. Usually the
                   SCR manufacturers will provide the full datasheet for those who want it.































                   Once you know
                   the pin outs of
                   the G, A and C
                   legs you can
                   begin to test the
                   SCR. If you
                   have the Peak
                   electronic atlas
                   component
                   analyzer tester,
                   what you need
                   to do is to
                   connect the three
                   small clips to
                   each pin of the
                   SCR (any part
                   number will do).

                   The tester will begin to analyze the SCR and prompt you with the display
                   such as “Sensitive or low power thyristor” before it tells you the exact pin
                   outs of G, A and C. After the first test, the tester will eventually show you
