Probing Electrical Connectors

Frontprobe
NOTE: Do not insert a DMM test probe into any connector or fuse block terminal The diameter of the DMM test probe will deform most terminals. A deformed terminal can cause a poor connection between the device, which can result in system failures. Always use the J 35616-A Connect Test Adapter Kit when using a DMM in order to probe terminals.
Important: When reconnecting connectors or replacing terminals always be sure to reinstall the Connector Position Assurance (CPA) and Terminal Position Assurance (TPA).

Important: After front probing any connector, check for terminal damage. If terminal damage is suspected, check for proper terminal contact.

When front probing connectors use a mating terminal adapter from the J 35616-A Connector Test Adapter Kit. Using the proper adapters ensures that proper terminal contact integrity is maintained.
Frontprobe connector terminals only when specifically required in diagnostic procedures. Because front probing can be a source of damage to connector terminals. Use extra 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.

Backprobe
Important:
- Do not backprobe a sealed connector.
- After backprobing any connector, check for terminal damage. If terminal damage is suspected, check for proper terminal contact.
