Place one test point on the primary terminal "D" (Fig 441) [this would be the point arm/spring] inside the distributer as in the first test and the other point on the switch casing "B" [pop-out exterior as in ground] With the switch locked the lamp should burn. [i.e. circuit continuity from points to ground] With the switch unlocked the lamp should not burn. [i.e. circuit open]

Age, time, and cycling wear may remove the grounding feature. Many pop-outs were replaced due to loss of ignition. One imagines not so many (probably none) due to loss of grounding.
The Service Bulletin section also talks about disassembly of the pop-out - but always starts the exercise with the switch unlocked.
