Test Lamp Jonnesway AR030052 6–24V Voltage Tester Probe

Jonnesway AR030052 is a 6–24V voltage tester probe designed for quick verification of DC circuits and common automotive electrical systems. The needle-tip probe gives access to tight contact points and exposed terminals while the built-in indicator shows the presence of voltage within the 6–24V range. The compact test lamp is intended for basic diagnostics, fault location and routine electrical checks on vehicles and other low-voltage installations.

Advantages

The tester offers a narrow needle-tip for precise contact with pins, terminals and small connectors, reducing the risk of shorting adjacent contacts. Its operating range of 6–24V covers the majority of vehicle and low-voltage DC applications. The clear visual indication simplifies detection of live circuits without the need for complex setup. The tool’s compact form factor makes it easy to carry and use in confined engine bays and wiring harness areas.

Suitable for

• Quick verification of 6–24V DC circuits in automobiles and motorcycles
• Locating blown fuses, open wires and faulty connectors
• Basic wiring checks on trailers, caravans and low-voltage installations
• Testing accessory power points and switches

Key specifications

• Operating voltage range: 6–24 volts DC
• Probe tip style: needle-point for access to small contacts
• Indication method: visual test lamp indicator
• Intended circuits: low-voltage DC systems and automotive electrical wiring
• Form factor: compact handheld probe

How to use

Connect the tester’s reference or ground lead to vehicle chassis or circuit negative, then touch the needle tip to the point to be tested. Observe the visual indicator to determine presence of voltage within the specified range. Apply steady contact to avoid bending the probe tip and keep the tester away from high-current terminals. Ensure ignition or circuit power is in the intended state (on/off) depending on the test being performed.

Usage recommendations

Use the tester only within its 6–24V DC rating and avoid contact with high-voltage circuits. Before probing, isolate circuits where possible and wear appropriate eye protection. Replace the tester if the insulation or probe tip is damaged to maintain safe and reliable operation.
