IMPORTANT: When performing a diode test on the rectifier/regulator, use only a digi-
tal meter with the capability of selecting a diode inspection mode.
NOTE: Due to differences in the manufacturing of ohmmeters, the internal polarity may vary.
As a result, the test readings may be a direct reversal of the readings specified. If so, reverse
the meter leads and perform the test again. A slight variance from the listed specification
does not necessarily indicate a defective component.

NOTE: All rectifier/regulator leads MUST BE disconnected to obtain accurate diode test
readings.
