TROUBLESHOOTING CABLES.
a.
General. Troubleshoot cables as an integral part of any radio system. The VIC interface cable
(CX-13313) and splitter cable (CX-13417) contain some components which cannot be checked with the
test equipment available to the unit maintainer. Other cables that cannot be repaired at this level are:
CX-13310, CX-13311, and CX-13312. These cables must be sent to DS Maintenance to be completely
tested.
N O T E
Paragraph 4.2 Cable Schematics, provides additional details regarding cable pins, connections,
and shielding.
b. Testing
(1) Continuity Test Procedure:
(a)
Disconnect cable from system being checked.
(b)
Set Multimeter (1) for continuity check (lowest ohm range).
(c)
Connect one test lead (2) to pin of connector (3) to be tested.
(d)
Connect other test lead to same pin of other connector (see Cable Schematics for details).
(e)
Cable is good if Multimeter (1) reads ZERO/short. Cable may be defective if Multimeter reads other
than ZERO/short; inspect for breaks, bad pins, loose connections, but do not attempt to repair
cables.
(f)
Replace faulty cable with a new or known good one.
