Rectifier Bridge Test.
(1)  Connect  an  ohmmeter  to  the
grounded heat sink and to one of the three terminals as
shown on figure 4-5. Check ohmmeter reading. Reverse
ohmmeter connections and again check reading. If both
readings are the same, replace the rectifier bridge. A
good rectifier bridge will give one high and one low
reading. Check each terminal against the heat sink in
the same manner.
