Automotive Voltage Tester GEKO G30804 6–24V Metal Probe with 90 cm Cable

GEKO G30804 is a handheld automotive voltage tester designed for 6–24V electrical systems. The tool combines a metal probe with a 90 cm insulated cable to reach battery terminals, connectors and wiring harnesses in cars, motorcycles and light commercial vehicles. It allows quick verification of presence of voltage, polarity and basic circuit continuity without the need for complex setup or power supplies.

Advantages

The metal probe provides reliable contact with terminals and connector pins while the insulated 90 cm cable gives extended reach into engine bays and confined spaces. The tool supports a 6–24V range common in automotive and motorcycle electrical systems and is portable for workshop, roadside or field use. Its simple construction reduces the chance of user error and lets technicians perform fast checks for voltage presence and basic diagnostics.

Suitable for

• Checking battery voltage and polarity on cars and motorcycles
• Verifying power at connectors and fuses
• Basic continuity and presence-of-voltage checks in wiring harnesses
• Quick roadside diagnostics and workshop troubleshooting

Key specifications

• Operating voltage range: 6–24 V DC
• Probe type: metal contact probe for direct terminal and pin access
• Cable length: 90 cm insulated lead for extended reach
• Intended applications: automotive, motorcycle and light commercial vehicle electrical systems
• Form factor: handheld tester suitable for portable use

How to use

Connect the insulated cable lead to the common or ground point as required by the vehicle's wiring layout, then touch the metal probe to the terminal, connector pin or wiring point to be tested. Observe the tester's indication method to determine presence of voltage and polarity; follow standard safety precautions when working on live circuits and avoid shorting contacts. For best results, ensure good metal-to-metal contact and test while the vehicle electrical system is in the appropriate state (e.g., ignition on or accessories enabled) for the circuit under inspection.

Usage recommendations

Use this tester only on 6–24 V DC systems and avoid applying it to higher-voltage circuits. Wear appropriate eye protection and disconnect power when performing repairs. Store the tester in a dry environment and inspect the insulation and probe for damage before each use.
