I have one of those polarity/line/ground checker plugs. It has three lamps
that illuminate according to the condition of the 120VAC outlet. The neon
light that illuminates indicating a good ground is not lighting up anymore.
Will this replacement neon light work properly for this application?

There is a 68k resistor in series with the lamp. What does the breakdown
voltage indicate?

A picture of a similar tester is here.
