Circuit inside of the diode rectifiers is as shown in Fig. 2-13. Check continuity between each terminal by
using a circuit tester as shown in Fig. 2-14. The rectifier is normal when condtinuity is as follows:

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.
