Loose connections (terminals)
Repair wiring and cable terminals, using appropriate procedures.
Loose connections in terminals may be caused by oxidation of the pins and sockets, or by a faulty connection of a cable to its cable terminal.
Loose connections produce the same faults as an intermittent open-circuit in a cable.
Checks:
- Inspect terminals visually according to "Inspect Terminals Visually". Continue according to "Contact Resistance and Oxidation".
