6-7.DIODE.STACK
Circuit inside of the diode stack is as shown in Fig .6-8a .
Check continuity between each terminal by using a circuit tester as shown in Fig .6-8b .
The diode stack 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.
