All-in-One Diagnostic Tool for 6-24V Automotive Electrical Systems
This 6-24V automotive circuit tester is your one-stop solution for vehicle electrical diagnostics:
- Covers 10+ core functions (voltage detection, diode test, continuity check, ground detection, etc.)
- Built-in overload protection + sound cues + floodlight for convenient operation
- Compact pen design + flexible probe – fits tight spaces in engines/wiring harnesses
Car Circuit Tester with Overload Protection
Why This Matters for Your Vehicle?
- Shields your car/truck’s electrical system from accidental overcurrent
- Works seamlessly with 6-24V DC systems (cars, motorcycles, boats, trailers)
Instant Polarity & Voltage Detection for 6-24V Systems
Why This Design Works for You
Whether you’re testing battery terminals, fuse boxes, or wiring harnesses:
- Visual + Digital Feedback: LEDs let you confirm polarity instantly, while the LCD gives precise voltage readings (6-24V DC)
- 10.2-Inch Length: The extended probe reaches tight spots (like engine bay wiring) without straining your hand
Works for All 6-24V Vehicles (Cars, Motorcycles, Vans & More)
Every Part Works for You
14.7FT (4.5M) Extension Lead: Reach across engine bays or under vehicles without moving the battery clamp
LCD Display + LED Alerts: Instantly see voltage/polarity (red/green LEDs) + precise digital readings
Battery Clamp + Grounding Clip: Secure, stable connections to your vehicle’s battery (no loose wires mid-test)
Buzzer & Power Switch: Audible alerts for continuity/overload; one-button power control for simplicity
