This automotive diagnostic kit combines a multi-function circuit tester with a dedicated tracer to identify shorts and opens in vehicle wiring. It functions as a DC/AC voltmeter and ohmmeter with specialized modes for testing fuel injectors and computer drivers. To pinpoint faults, the tracer utilizes directional indicators and distance-from-source signals to track the path of a circuit to the exact location of a break or short.
