Find vehicle electrical faults with one probe that lets you test circuits, trace wiring, and activate components without switching tools.
-
Multiple tests: Check AC/DC voltage, 8–100 kΩ resistance, diodes, polarity, continuity, grounds, and components; test relays, fuses, and trailer lights.
-
Trace circuit faults: Locate open circuits, shorts, broken wires, and electrical signals in circuit-breaker mode, with tracing specified for 6–42V DC.
-
Vehicle voltage range: Use with 12V or 24V systems; voltage testing is specified for 9–30V DC.
-
Reach and visibility: The 40 ft/12 m cable includes a 20 ft built-in lead and 20 ft extension. A cigarette lighter adapter, probe-tip light, 168 × 128 TFT color display, and overload protection support testing in hard-to-reach areas.
