8-6 DIODE RECTIFIER
Fig. 5
Fig. 6
Circuit inside of the diode rectifiers is as shown in Fig. 5. Check continuity between each terminal by using
a circuit tester as shown in Fig. 6. The rectifier is normal when continuity is as follows:
NOTE 1: In checking the diode, direction of connection is contrary to the ordinary case because of
characteristics of the diode and battery incorporated in the tester.
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.
