Power Probe III Continuity Tester

Power Probe III gives an instant hot lead or ground lead with the press of a switch. Use the probe tip and ground lead simultaneously to power up components right in your hand. Instantly check components for continuity as well as identify positive, negative and open circuits without re-polarizing hook-up clips. Locate shorts without wasting fuses. The 20 ft lead will allow you to test bumper to bumper without jumper leads. Audio tone indicates positive with a high pitched tone and negative by a low pitched tone.
