What Power Probe 1 can do for you:

When you connect your Power Probe to the car battery you will have a multitude of testers at your finger tips. With the press of a switch you'll have an instant hot lead or ground lead. Use the hot and ground lead simultaneously to activate components right in your head. Instantly check components for continuity as well as identify positive, negative and open circuits without re-polarizing hook-up clips. Follow and locate shorts without wasting fuses. The 20ft lead will allow you to test bumper to bumper without jumper leads.
