This test methodology applies to both D2 and D3. Turn off power at utility disconnect and
lock/tag disconnect. Remove upper rear panel of Power Supply Cabiner. Unplug connections to
rectifier. Using Diode Test mode on your DMM, measure voltage across the following points on
rectifier:
DC+ to AC Inputs
DC- to AC Inputs
If any voltage measurement is less than 0.1VDC, replace rectifier and re-test.
