Avalanche 2500 2WD V8-8.1L VIN G (2002)
NOTE: Refer to Test Probe Notice in Service Precautions.
A test lamp can simply and quickly test a low impedance circuit for voltage.
The J 34142-B 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.
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.
Using Connector Test Adapters
NOTE: Do not insert test equipment probes into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A
deformed terminal can cause a poor connection, which can result in system failures. Always use the J 35616-A Connector Test Adapter Kit or the J
42675 Flat Wire Probe Adapter kit in order to frontprobe terminals. Do not use paper clips or other substitutes as they can damage terminals and cause
incorrect measurements.
Using Fused Jumper Wires
TOOLS REQUIRED
J 36169-A Fused Jumper Wire
IMPORTANT: A fused jumper may not protect solid state components from being damaged.
The J 36169-A includes small clamp connectors that provide adaptation to most connectors without damage. This fused jumper wire is supplied with a
20-A fuse which may not be suitable for some circuits. Do not use a fuse with a higher rating than the fuse that protects the circuit being tested.
