9A-152 Wiring Systems:
Using Connector Test Adapters
CAUTION
!
Do not insert test equipment probes (DVOM etc.) into any connector or fuse block terminal. The
diameter of the test probes will deform most terminals. A deformed terminal will cause a poor
connection, which will result in a system failure. Always use the J-35616 GM-Approved Terminal Test
Kit in order to front probe terminals. Do not use paper clips or other substitutes to probe terminals.
When using the J-35616 GM-Approved Terminal Test Kit, ensure the terminal test adapter choice is the
correct size for the connector terminal. Do not visually choose the terminal test adapter because some
connector terminal cavities may appear larger than the actual terminal in the cavity. Using a larger
terminal test adapter will damage the terminal. Refer to the J-35616 GM-Approved Terminal Test Kit
label on the inside of the J-35616 GM-Approved Terminal Test Kit for the correct adapter along with the
connector end view for terminal size.
Probing Electrical Connectors
NOTE
Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance
(TPA) when reconnecting connectors or replacing terminals.
Frontprobe
Disconnect the connector and probe the terminals from the mating side (front) of the connector.

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 proper adapter for 0.64 terminals is the J 35616-
64B which has a gold terminal and a black wire between the base and tip. Failure to use the proper test
adapter may result in damage to the terminal being tested and improper diagnosis.
Refer to the following table as a guide in selecting the correct test adapter for frontprobing connectors:
