Section IX. MAINTENANCE OF ELECTRICAL SYSTEM
4-26. General. This section of the manual contains unit level maintenance procedures for electrical
components that are unique to the AN/MJQ-10A power plant. Specifically, this includes the switch box and the
power cables.
4-27. Cable Testing. A continuity test is used to detect opens or shorts in the power plant power cables. The
two cables differ from each other only in length. The following test procedure is typical for both.
a.
b.
c.
d.
e.
f.
Set multimeter controls to prepare unit for continuity testing.
NOTE
The contacts in the connector end of cable are labeled A, B, C, N, and G1 thru G4. The
individual colored wires at the other end of cable are labeled L0, L1, L2, L3, and GEN
GND.
Touch one probe to contact A in connector and touch remaining probe to black wire labeled L1. Multimeter
must indicate continuity. If it does not, cable is open.
With first probe still in contact A, touch remaining probe to wires labeled L2, L3, L0, and GEN GND.
Multimeter must not indicate continuity. If it does, cable is shorted.
Refer to figure 4-13, and repeat steps b. and c. at connector contacts B, C, and N. In each case, continuity
must exist between corresponding points and only between corresponding points.
Connect one multimeter probe to GEN GND lug on cable and touch remaining probe to G1, G2, G3, and
G4. Continuity must be indicated on each contact.
If continuity test detects any opens or shorts in cable, refer cable to higher level of maintenance.
