Voltage Tester Pen Jonnesway AR030005 — Needle Tip 6–12 V

Needle-tip voltage tester pen Jonnesway AR030005 — Needle Tip 6–12 V is a compact diagnostic tool designed to detect DC voltage within the 6–12 V range. The pointed probe enables precise contact testing of small terminals, connector pins and tight wiring spaces commonly found in automotive and low-voltage electrical systems. This tester is intended for quick presence/absence voltage checks on batteries, connectors and circuits during routine maintenance and repair work.

Advantages

The needle-tip design provides accurate contact with miniature terminals and recessed connectors, reducing the risk of slipping or shorting adjacent contacts. Its small form factor allows access in confined engine bays and control panels where larger testers cannot reach. The tester requires minimal setup and delivers fast visual indication of DC voltage, helping technicians and DIY users perform efficient troubleshooting without complex equipment.

Suitable for

• Checking 6–12 V vehicle wiring and battery circuits
• Testing small connectors, sensor pins and fuse contacts
• Inspecting low-voltage control circuits and accessories
• Fast verification of voltage presence during diagnostics and repairs

Key specifications

• Measured voltage type: DC
• Detection range: 6–12 V
• Probe type: needle-point metal probe for precise contact
• Form factor: compact pen-style housing for confined spaces
• Operation: contact testing for presence/absence of voltage

How to use

To test a circuit, connect the tester’s reference or ground lead according to the manufacturer’s instructions, then touch the needle probe to the target terminal or conductor. Observe the tester’s indicator to determine the presence or absence of DC voltage within the 6–12 V range. Use steady contact and avoid sliding the probe across exposed conductors to minimize the risk of accidental shorts. Perform tests with the vehicle or equipment powered as required for the specific diagnostic task, following standard safety precautions.

Usage recommendations

Use appropriate personal protective equipment and ensure the reference/ground connection is secure before probing. Do not use the tester on circuits outside the specified 6–12 V DC range and avoid exposing the pen to moisture or corrosive environments. Store the tester in a dry place and inspect the needle probe for damage before each use.
