Test Lamp

NOTE: Refer to Test Probe Notices in Service Precautions

A test lamp can simply and quickly test a low impedance circuit for voltage.

The J 34142-B Test Lamp 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 procedure.
^ 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.
