Note #1: Short circuits can usually be located in the cells or ionizer by inspection. (See "CAUTION" ).
Check for broken ionizer wires, bent cell plates, dirt between plates or dirty components.
If
the fault cannot
be located by inspection, localize the trouble by alternately disconnecting the high voltage cables at the cells,
ionizer and capacitor terminals. Repair or replace the defective part. For power pack short circuits, first
check the rectifier tubes. Next inspect the wiring for grounds and then test the transformer and capacitor or
try replacing them until the fault is corrected.
Note #2: If a d.c. high voltage meter is available, measurement of the ionizer
&
cell voltages is helpful in
locating troubles. See "CAUTION". Ionizer voltage should
be
12.5
:!:"
0.5 KV and cell voltage 6
:!:"
0.5 KV. Us­
ually these voltages will
be
low when there is a high voltage short circuit.
