2. Checking when a connector is disconnected:
Check by pulling the wire harness lightly from the backside of the connector. Look for unlatched terminals, missing terminals, loose crimps or
broken conductor wires. Check visually for corrosion, metallic or foreign matter and water, and bent, rusted, overheated, contaminated, or
deformed terminals.
3. Checking the contact pressure of the terminal:
Prepare a spare male terminal. Insert it into a female terminal, and check for ample tension when inserting and after full engagement.
NOTE: When testing a gold-plated female terminal, always use a gold-plated male terminal.
d. REPAIR METHOD OF CONNECTOR TERMINAL
1. If there is any foreign matter on the terminal, clean the contact point with compressed air or a cloth. Never rub the contact point using
sandpaper as the plating may come off.
2. If there is abnormal contact pressure, replace the female terminal. If the male terminal is gold-plated (gold color), use a gold-plated female
terminal; if it is silver-plated (silver color), use a silver-plated female terminal.
3. Damaged, deformed, or corroded terminals should be replaced. If the terminal does not lock into the housing, the housing may have to be
replaced.
e. HANDLING OF WIRE HARNESS
1. If removing a wire harness, check the wiring and clamping before proceeding so that it can be restored in the same way.
2. Never twist, pull or slacken the wire harness more than necessary.
3. The wire harness should never come into contact with a high temperature part, or rotating, moving, vibrating or sharp-edged parts. Avoid
contact with panel edges, screw tips and other sharp items.
4. When installing parts, never pinch the wire harness.
5. Never cut or break the cover of the wire harness. If it is cut or broken, replace it or repair it with vinyl tape.
