5-2.2.1
Normal DC voltage with near zero current indicates a break in the anode
lead, failed anodes, or a break in the structure lead (proceed to paragraph 5-2.3).
5-2.2.2
Half the normal current output indicates either a
defective diode/selenium
plate; a break in the header cable between anodes; or, if there are multiple anode leads,
loss of one anode lead or anode bed. Measure the DC voltage output of the rectifier
with a handheld multimeter on the DC volts scale. Measure voltage from N4 to P4. If
