5. Connect the negative lead of the DMM to a good ground.
6. The DMM displays the voltage measured at that point.

Measuring Voltage Drop
Notice: Refer to Test Probe Notice.
The following procedure determines the difference in voltage potential between 2 points.
1. Set the rotary dial of the DMM to the V (DC) position.
2. Connect the positive lead of the DMM to one point of the circuit to be tested.
3. Connect the negative lead of the DMM to the other point of the circuit.
4. Operate the circuit.
5. The DMM displays the difference in voltage between the 2 points.

Important: 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.
Important: When probing female.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.64 terminals is the J35616-64A which has a tin terminal and a blue 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.
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 J35616 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 J35616 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 J35616 GM-Approved Terminal Test Kit label on the inside of the J35616 GM-Approved
Terminal Test Kit for the correct adapter along with the connector end view for terminal size. Refer to the following table as guide in selecting the
correct test adapter for frontprobing connectors:
