8.3 cm Chrome-Vanadium (Cr-V) Needle Probe
Constructed from hardened carbon Chrome-Vanadium steel that resists bending and corrosion while easily contacting narrow connector pins and fuse test points.
Bright 3-Watt Built-In Indicator Bulb
Housed inside the transparent ABS handle, the 3W test lamp illuminates clearly whenever voltage is present, even in bright workshop lighting.
96 cm Flexible Cable & 20A Ground Clamp
Provides ample reach from the battery negative terminal or chassis ground to under-dash fuse panels and exterior lighting harnesses.
APPLICATIONS & CIRCUIT DIAGNOSTICS
Rapid Troubleshooting Across Vehicle Wiring Harnesses
Essential electrical checks where physical voltage verification is required:
- Fast Fuse Testing: Touch both top test tabs of blade fuses without removing them from the fuse box to immediately spot blown fuses
- Lighting & Trailer Sockets: Verify power at headlights, brake lights, turn signals, reverse lights, and 7-pin/13-pin trailer connectors
- Broken Wire & Socket Tracing: Test starter trigger wires, horn circuits, cooling fan switches, fuel pump feeds, and door boot harnesses
- Accessory Installation: Quickly identify constant +12V (B+) and ignition-switched +12V (ACC) wires when installing stereos, dashcams, or sensors
BUILD QUALITY & ERGONOMIC DESIGN
Workshop-Grade Materials for Daily Use
Engineered for durability and safe handling:
- Insulated ABS Handle: 17.3 cm screwdriver-shaped impact-resistant transparent ABS handle for a secure grip
- Chrome-Vanadium Steel Probe: 8.3 cm sharpened conductive tip with protective safety cap
- Strain-Relief Spring & 20A Clamp: Flexible spring guard at the handle exit prevents wire fatigue
SAFE OPERATION GUIDELINES
How to Use the 6V-24V Circuit Tester
Simple steps for accurate and safe circuit testing:
- Connect Ground Clamp: Attach the 20A alligator clip to the battery negative (-) terminal or a clean bare-metal chassis ground.
- Probe the Target Circuit: Touch the steel needle tip to the fuse tab, connector pin, or wire; the 3W bulb lights up when 6V-24V DC power is present.
- Safety Advisory: Designed strictly for 6V-24V DC low-voltage vehicle systems; never use on 110V/220V AC household mains.

Workshop Application & Operating Guide
Recommended 4-step standard procedure for accurate results.
Attach Ground Clip
Clip the 20A alligator clamp onto the vehicle's negative (-) battery post or a clean metal chassis ground.
Touch Fuse or Connector Pin
Place the 8.3 cm Chrome-Vanadium needle probe onto the fuse test point or socket terminal.
Check 3W Indicator Light
If 6V-24V power is present, the 3W handle bulb illuminates; if only one side of a fuse lights up, the fuse is blown.
Store With Protective Cap
Disconnect the ground clamp after testing and place the protective cap over the needle tip.
Technical Capabilities & Operational Advantages
Key engineering advantages for professional workshop diagnostics.
Core Workshop Requirements
- Flimsy testers with short leads that cannot reach from chassis ground to the fuse panel
- Soft metal probes that bend easily or corrode in workshop environments
- 12V-only bulbs that burn out immediately when testing 24V trucks or trailers
- Pulling fuses out one by one with pliers just to find a blown circuit
With 6V - 24V Oto Elektrik Devre Tesisatı Kontrol Kalemi (Cr-V Çelik Problu)
- Generous 96 cm flexible cable and 20-Amp ground clamp for easy reach
- Hardened 8.3 cm Chrome-Vanadium steel needle probe and 17.3 cm ABS handle
