TEST DESCRIPTION
This test will determine if the stator is able to produce correct voltage from of its windings.
It will only yield meaning data if the engine high idle speed is correct, (1860 to 1890 RPM),
and approximately 160 VDC is present across the rotor slip rings.
NOTE: The slip ring voltage will most likely be correct if at least one of the AC output volt-
ages is correct.
