Downloaded from www.Manualslib.com manuals search engine How To Check Electrical Connectors
Many electrical problems are caused by faulty electrical connections or wiring. It is also possible for a sticking com-
ponent or relay to cause a problem. Before condemning a component or wiring assembly always, check the electrical
connectors for good continuity.
How To Probe Connectors
•Connector damage and an intermittent connection can result from improperly probing the connector during cir-
cuit checks.
• The probe of a DMM may not correctly fit the connector cavity. To correctly probe the connector, follow the pro-
cedures below using a “T” pin. For the best contact, grasp the “T” pin using an alligator clip.
Probing From Harness Side
•If the connector has a rear cover connector, remove the rear cover before probing the terminal.
• Do not probe waterproof connectors from the harness side. Damage to the seal between the wire and connec-
tor may result.
Probing From Terminal Side
•Female Terminal:
Do not insert any object into the female connector that is bigger than the male terminal.
• Male Terminal:
Carefully probe the contact surface of each terminal using a “T” pin. Do not bend terminal.
How To Check Proper Contact Spring Tension Of Terminal
•An enlarged contact spring of a terminal may create intermittent signals in the circuit.
• If an intermittent open circuit occurs, follow the procedure below to inspect for open wires and enlarged contact
spring of female terminal.
Use a male terminal which matches the female terminal.
Disconnect the suspected faulty connector and hold it terminal side up.
While holding the wire of the male terminal, attempt to insert the male terminal into the female terminal.
While moving the connector, check whether the male terminal can be easily inserted or not.
NOTE :
If the male terminal can be easily inserted into the female terminal, replace the female terminal.
