Figure 1-8 How to Clean Gold-Plated Terminal
Note 1:
Use cloth (gauze, etc.) to clean.
Note 2: After wiping, be careful not to leave lint on the surface of the circuit card.
(6) When a check on the flat cable or LT cable is directed in the tree, check the following items:
(a) Make a visual check to see if the connector is properly connected.
(b) Poor connector contact may be responsible for the fault. Repeat connection and disconnection a few
times, and check again to see if the connector is properly connected.
(c) Perform continuity test on the flat cable.
(7) When replacing the circuit card is directed in the tree, replace the circuit card with a spare as per Chapter 5.
(8) When multiple circuit cards appear faulty, before replacing them with spares, remount them (one at a time)
into their slots, to determine which cards should be replaced.
