With the long lead provided (12+ feet) you can hook up to your car battery and go around the car and test the operation of various electrical components. Kent decided to test its maximum reach. You can see in the picture below that it will "almost" power the wiper motor in a 300TD wagon with the hatch open. What we particularly like about this tester is the probe tip and clamp are small enough that you can test very small components like dash bulbs shown below. Sure beats carrying around a battery or booster pack with jumper leads attached to do you testing!
