3-8. Wiring Fault Isolation. If a malfunction occurs in the wiring harness, cabling, or circuit card connectors, remove all
circuit cards and disconnect all cable connectors. Use the wire lists to check wiring in the following example:
WARNING
HIGH VOLTAGE is used in the operation of this equipment. DEATH ON CONTACT
may result if personnel fail to observe safety precautions. Learn the areas containing
high voltage in each piece of equipment.  Be careful not to contact high voltage
connections when installing or operating this equipment.
Before working inside the equipment, turn power off and ground points of high potential
before touching them.
a. If signal name is unknown, use string list (see figure 3-2) to identify signal. Locate connector and pin number in
the FROM column (J2146, pin 15), then find the signal name under the SIGNAL column (HADAFO) to the right
of connector and pin number.
b. Check continuity between connections indicated under CONNECTOR and PIN headings in FROM column
(J2146, pin 15) and connections indicated under CONNECTOR and PIN headings in TO column (J2109, pin 15).
Check continuity for each listing of signal (HADAFO) in SIGNAL column.
c.
To use the logic list, refer to the connector list example (see figure 3-1) or string list example (see figure 3-2),
and locate in the EQUATION column HAT021E. Proceed to logic list example (see figure 3-3) and locate in the
EQUATION column HAT021E. The FACTOR column identifies the logic factors needed to generate specific
functions.
