MIL-HDBK-1023/4
(2) Figure 34 illustrates how two loads are "integrated" into one load circuit for the
purpose of locating the load-to-load short location. The two regulator loads have been split at
the short location. Now, driving the load will locate the on/off transition of the lights and locate
the short.

Single Load-to-Load Short Circuit Integration Method
Caution: The disconnected cables (L2-A and L2-B in the illustration) have high voltages on
them during this test. Provisions should be made to protect personnel from coming in contact
with these disconnected cables.
Caution: Never integrate a 20.0 ampere regulator onto a 6.6 ampere load. The 20.0 ampere
regulator will surely blow out all of the 6.6 ampere lamps. If a 20.0 ampere load and a 6.6
ampere load become shorted together, troubleshoot the circuit with the 6.6 ampere regulator. It
will still be possible to locate the short looking for the on/off transitions.
