Danger: This procedure should not be performed on high voltage circuits. Performing this procedure on high voltage circuits may result in serious injury or death.
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.The following procedure tests for a short to voltage in a circuit.
- Set the rotary dial of the DMM to the V (DC) position.
- Connect the positive lead of the DMM to one end of the circuit to be tested.
- Connect the negative lead of the DMM to a good ground.
- Turn ON the ignition and operate all accessories.
- If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit.
