Which inspection applies to a suspect network connector?

  • A.Nothing
  • B.Check each terminal for green corrosion, for pins that have been spread, and for wires pushed back out of the housing
  • C.Examine the terminals for corrosion, spread and back out
  • D.Measure the resistance across the connector, which reveals any additional resistance introduced by the joint

Answer: C

Spread terminals and pushed back pins are as common as corrosion and are found only by looking. The last option lists exactly those three defects, which makes it a correct and more detailed version of the same answer. The order in which the effects act is what decides the outcome, so it is worth establishing first. Working the distinction through on a single concrete case fixes it more firmly than any rule of thumb. Checking which component actually carries the load settles most questions of this kind at once.
