Section 8A-2 - Electrical Diagnosis, Piercing Wire Insulation during Electrical System Diagnosis

The 1994 and prior Driveability, Emissions & Electrical Diagnosis Manuals incorrectly state "The 12-Volt test lamp generally has a sharp probe tip so it can be inserted into connector terminals or through the wire insulation for testing. It is important to keep the probe tip sharp to minimize damage to wire insulation." Please disregard this statement.
DO NOT pierce wire insulation when performing electrical system diagnosis because it will damage the wiring harness. Always use Kent-Moore Connector Test Adapter Kit J 35616-A when testing or taking measurements of electrical systems and components.
