J 35616-200 Test Light - Probe Kit
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.A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present.
The J 35616-200 is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads.
To properly operate this tool use the following procedures.
When testing for voltage:
- Attach one lead to ground.
- Touch the other lead to various points along the circuit where voltage should be present.
- When the bulb illuminates, there is voltage at the point being tested.
When testing for ground:
- Attach one lead to battery positive voltage.
- Touch the other lead to various points along the circuit where ground should be present.
- When the bulb illuminates, there is ground at the point being tested.
