Using Connector Test Adapters
Using Connector Test Adapters
Notice: Do not insert test equipment probes into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal can cause a poor connection, which can result in system failures. Always use the J 35616 GM-Approved Terminal Test Kit in order to frontprobe terminals. Do not use paper clips or other substitutes as they can damage terminals and cause incorrect measurements.
When using the J 35616 GM-Approved Terminal test kit, ensure the terminal test adaptor choice is the correct size for the connector terminal. Do not visually choose the terminal test adaptor because some connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger terminal test adaptor will damage the terminal. Refer to the label on the inside of the J 35616 GM-Approved Terminal test kit for the correct adaptor along with the connector end view for terminal size.
