ABSTRACT:
An electrical test lead includes an insulated electrical cable having a proximal end and a distal end, an electrical connector disposed at the proximal end of the cable and connected to a test instrument, and an electrically conductive magnetic probe disposed at the distal end. The probe is adapted to magnetically attach to a test point in an electrical system and to provide an electrical connection from the test point through the probe, the cable and the connector to the test instrument. Together, the test lead and the test instrument may be used as an electrical test kit. The test lead may further include an additional electrical test lead component magnetically attached, and electrically connected, to the electrically conductive magnetic probe and extending therefrom. An additional electrically conductive magnetic probe or a non-magnetic electrical connector may be disposed at the distal end of the additional electrical test lead component.
