Troubleshooting with a Test Lamp
Troubleshooting with a Test Lamp
Special Tools
J 35616-200 Test Light - Probe Kit
Caution: Refer to Test Probe Caution (See: Service Precautions/Vehicle Damage Warnings/Test Probe Caution).
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:
1. Attach one lead to ground.
2. Touch the other lead to various points along the circuit where voltage should be present.
3. When the bulb illuminates, there is voltage at the point being tested.
When testing for ground:
1. Attach one lead to battery positive voltage.
2. Touch the other lead to various points along the circuit where ground should be present.
3. When the bulb illuminates, there is ground at the point being tested.
Testing for a Short to Voltage
Testing for a Short to Voltage
Caution: Refer to Test Probe Caution (See: Service Precautions/Vehicle Damage Warnings/Test Probe Caution).
The following procedure tests for a short to voltage in a circuit.
1. Set the rotary dial of the DMM to the V (DC) position.
2. Connect the positive lead of the DMM to one end of the circuit to be tested.
