Fast Detect and Easy to Use
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
Work Anywhere, Even in Low-Light Spaces
Car Circuit Tester with Built-In Floodlight: Diagnose in Dark Engine Bays Easily
For mechanics or DIYers:
- One-Handed Operation: Hold the tester and light the area with one hand – free the other to adjust wires or connectors
- No More Shadows: The probe-mounted light targets exactly where you’re testing (no glare, no missed details)
- All-Weather Utility: Works in dark, cramped spaces (trailer wiring, RV compartments) that standard flashlights can’t reach
Know Positive/Negative Poles at a Glance
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)
- Positive Pole Alert: When the probe touches a positive electrode, the front red LED lights up – plus the blue LCD shows real-time voltage
- Negative Pole Alert: Touch a negative electrode (or reverse-activate), and the green LED turns on (LCD still displays voltage)
Comfortable Grip
10.2-Inch Car Circuit Tester Pen
The extended probe reaches tight spots (like engine bay wiring) without straining your hand
Works for All 6-24V Vehicles (Cars, Motorcycles, Vans & More)
