Electrical Connector Probing

Only 2 methods of electrical connector probing are allowed.

1. Probing at the rear of unsealed electrical connectors (see illustration E190832).
2. Probing on the conductor crimp of an extracted terminal (see illustration E190928).
   • The conductor crimp is the portion crimped to the non-insulated wire.
   • This method may be used on sealed or unsealed connectors, but method 1 is preferred for unsealed connectors.
     CAUTION:

     • A suitable sized probe must be used. If the probe is larger than the electrical connector aperture, then damage to the electrical connector will occur.
     • The probe must only be inserted into the rear of the electrical connector for a distance sufficient to contact the terminal.
     • Take care not to bend or distort any part of the metal terminal wire crimp area with the probe.
     • Before extracting any terminals, refer to the Electrical Connector Terminal Extraction  and Extraction Tools  sections of this document for more information.
     • Probing must NOT be carried out on; either the connector contact area or the portion of the terminal that is crimped to the insulated part of the wire.
     • Make sure the terminal is correctly and securely located in the electrical connector after re-installation.

Method 1 

Method 2 

The following 2 methods of electrical connector probing are not allowed.

1. Probing at the rear of sealed electrical connectors (see illustration E190926).
2. Probing at the electrical connector contact area (see illustration E190927).
