Secondary Short Circuit
The most common outage is a short in the secondary
circuit and is best located through the process of
elimination. Symptoms are a flickering indicating light
accompanied by an arcing noise in the ionizingcollecting
cells or an indicating light that is not glowing.
A flickering light with an arcing noise is an indication of
a high resistance short circuit and a light that is not
glowing is an indication of a dead short. (A light that is
not glowing can also be an indication of an open circuit
in the primary circuit. Refer to the paragraph on open
circuits.) The short may be in the power supply, the
high voltage lines or the ionizing-collecting cells. To
isolate the short to any one of these three components,
proceed as follows
