Probing Electrical Connectors

 

Special Tools

 EL 35616Terminal Test Probe Kit

For equivalent regional tools, refer to Special Tools.

Note

Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or replacing terminals.


 Front probe

Disconnect the connector and probe the terminals from the mating side (front) of the connector.

Refer to Test Probe Caution

Note

When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64 terminals. The correct adapter for 0.64 terminals is J-35616-64B. It has a gold colored terminal and black lead between its base and top. Failure to use the proper test adapter may result in damage to the terminal being tested and improper diagnosis.


Note

J-35616-35 is the correct adapter for testing terminals for fuses, relays or diodes in an electrical centre. The terminal being tested could be damaged if any other tool or adapter is used.


Refer to the following table as a guide in selecting the correct test adapter for front probing connectors:

 Backprobe

Note
• Backprobe connector terminals only when specifically required in diagnostic procedures.

• Do not backprobe a sealed (Weather Pack®) connector, less than a 280 series Metri-Pack connector, a Micro-Pack connector, or a flat wire (dock and lock) connector.

• Backprobing can be a source of damage to connector terminals. Use care in order to avoid deforming the terminal, either by forcing the test probe too far into the cavity or by using too large of a test probe.

• After backprobing any connector, inspect for terminal damage. If terminal damage is suspected, test for proper terminal contact.


Do not disconnect the connector and probe the terminals from the harness side (back) of the connector.
