I opened it up and the crimps and resistors are good.

Well, so much for the easy fix.

When you inscribed:
"The neon light that illuminates indicating a good ground
is not lighting up anymore".
Which of the 3 lamps are you referring to?

I would guess(tm) that this is what you found inside:

Do you have any idea
what the lamp's breakdown voltage specification indicates? According to the
datasheet, the NE-2 has a breakdown voltage of 65VAC. The high brightness
bulbs have a higher breakdown voltage of 95VAC.

It's not a high brightness NE-2H or NE-2UH lamp.

Neon lamps have a V/I curve with hysteresis. They turn on at about
65VAC, and stay turned on until the voltage drops below about 50VAC
(maintaining voltage). The actual voltages are not very well
controlled and are affected by ambient lighting, radiation, and
temperature. In between these two points, the neon lamp exhibits
negative resistance, which makes a dandy relaxation oscillator or
logic circuit.

Drivel: I'm reading from the "GE Glow Lamp Manual" 2nd edition 1966.
GE never made an NE-2. The closest equivalent is their 3AG lamp).
