(2) Figure 40 is an illustration of our second test using the manual ground method.
The manual ground from the first manual ground location has been moved to the midpoint of the
suspect section, illustrated at the manual ground #2 location.
SUSPECT PORTION OF CIRCUIT
INSTALL SECOND MANUAL GROUND ON MIDPOINT OF REMAINING LOAD.
Ungrounded Open on Load Circuit - Manual Ground Method Second Test
Turning on the regulator, the regulator tripped off in an open circuit condition, which reveals that
we passed over the open circuit as we proceeded into the suspect portion of the load from our
first manual ground location. Logic dictates that the open is probably between the present
second manual ground location and our first manual location. However, we would like some
proof (see Figure 41).
