Diagnose live wires and pinpoint electrical faults in your vehicle’s wiring harness with this battery-free automotive circuit tester that provides instant voltage confirmation through an integrated LED display.
- Confirm active circuits and isolate faulty connections using the included multi-tip probes designed for standard automotive fuses, relays, and wiring terminals.
- Trigger a clear LED signal the instant your probe contacts a live wire, delivering straightforward visual verification while you inspect dashboards or engine bays.
- Rely on the harness itself for power instead of internal batteries, so you can test continuously without worrying about dead cells or replacements.
- Keep the slim profile near your workbench or drop it straight into your tool roll to reach confined panels where standard multimeters fail.
