5-14. UNIT MAINTENANCE OF THE REMOTE CONTROL CABLE ASSEMBLY. Unit maintenance of the RCM cable
assembly (34, Figure 5-1) is limited to testing of the cable assembly.
Disconnect the RCM cable assembly in accordance with paragraph 5-12.
Set a multimeter to RX1 scale and test RCM cable assembly. Check for isolation between adjacent conductors,
and between any conductor and ground. Multimeter should read infinite resistance for each test.
Check each conductor for continuity from one plug connector to the other. Multimeter should read zero
resistance from one end of any conductor to the other.
If tests fail to show Isolation or continuity, refer to the next higher level of maintenance for repair and overhaul
of the defective RCM cable assembly.
