(3) DIODE RECTIFIER
The circuit inside the diode rectifiers is as shown in the chart above.
Check continuity between each terminal by using a circuit tester.
The rectifier is normal when continuity is as follows:

(4) AC RECEPTACLES
Check that no live part or wire or plastic part is burnt.
NOTE 1 : Because of the difference of measuring method between the analogue circuit tester and the digital circuit
tester, polarity of tester needles should be reversed.
NOTE 2 : "Continuity" means forward direction characteristics of the diode, and different from short circuit condition
(in which a pointer of the tester goes out of its normal scale), shows resistance to some extent.
When results of the checking indicates failure even in one section, replace with a new one.
NOTE 3 : Some analogue testers like "Simpson" brand operate as some as digital testers.
