Procedure

1. 8. Test a third diode as follows:
2. a.Connect one VOM test lead to the white wire, the
3. other test lead to transfer mechanism terminal B1.
4. Note the meter reading.
5. b. Now, reverse the polarity (reverse the VOM test
6. leads). Note the reading.
7. c. The diode's forward resistance should be indi-
8. cated at one polarity only, “Infinity” at the opposite
9. polarity. WHITE .
10. 9. Test the fourth bridge rectifier diode as follows: AC GRAY 1 .
11. a. Connect first VOM test lead to the red wire, the
12. second test lead to terminal B1. Note the meter
