For 1990-2009 cars only
Notice: 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.This test checks for voltage being lost along a wire or through a connection or switch.
- Connect the positive lead of a DMM to the end of the wire or to one side of the connection, or to the switch whichever is closer to the battery.
- Connect the negative lead to the other end of the wire or to the other side of the connection, or switch.
- Operate the circuit.
- The DMM will show the difference in voltage between the two points.
