Section IV. TROUBLESHOOTING
3-10. Power Unit Troubleshooting . There are no troubleshooting procedure authorized at operator level for
the power unit end item. However, since the field configuration involves two identical interconnected power
units, thereby providing the operator with two complete sets of cables, cable substitution may be used to test
and cor-rect malfunctions when there is reason to suspect that the cause is a faulty cable. Cables that may be
substituted by the operator are the power/control cable (PDU connector J1 to the ICC/CRG), the control cable
(PDU connector J6 to the ICC/CRG), the auxiliary cable (PDU connector J10 to the standby power unit) and the
P4, P7 fuel cable (adapter plate assembly connector J4 to the fuel tank fuel level sensor). In addition, the 75-
foot power/control cable and the 25-foot auxiliary cable are identical except for length, so that either one may
serve as a substitute for the other when testing. As a corrective action, however, the auxiliary cable may be
replaced with a power/control cable, but the power/control cable may not be replaced with an auxiliary cable.
