NOTE:  Do not fill the protective cover with grease.

-

Press grease, P/N 1161417-9, into the female sockets directly from tube

-

Check that all the terminal cavities are filled

Open-Circuit, Permanent Faults

Open-circuit, permanent faults

An open-circuit in a cable is indicated by a loss of one or more functions.
Chafed and broken cables or terminals that have come loose are common causes of faults in electrical systems.

Repair wiring and cable terminals, using appropriate procedures. 
 
Checks:

-

Disconnect the connectors at both ends of the cable.

Connect an ohmmeter between the ends of the cable.
The ohmmeter should read approximately 0 [ohm] if there is no open-circuit in the cable

If the reading is not correct. Replace the cable and/or continue, according to "Contact Resistance and Oxidation"
