6V-30V DC Electrical System Tool

The VDIAGTOOL V100 PRO is a multifunctional power circuit probe tester designed for automotive electrical troubleshooting. It suits professional mechanics and DIY owners working on cars, SUVs, RVs or motorcycles who need to diagnose faults without guesswork. The tool combines eight detection capabilities in a single handheld unit. It is not for buyers who require high-voltage testing above 30V DC or oscilloscope-level waveform analysis.

Check Vehicle Voltage Range and Access Points

Before ordering, confirm the vehicle electrical system operates within the 6V to 30V DC range supported by this tester. Ensure you can safely disconnect power for in-circuit component testing as required by the manufacturer. Verify that probe tips can reach tight locations such as under dashboards, door interlayers, handbrake gaps and rear seat rails where faults often hide. The tool is not suited for systems outside the stated voltage window or for non-automotive high-current industrial circuits.

14.7ft Extension Cable and Component Activation

The bundled 14.7ft extension cable extends reach around the vehicle without moving the main unit. Battery hookup clips provide a secure power source connection for the tester itself. Component activation function lets you power up fuel pumps, window motors, blower motors and solenoids directly to isolate defective parts offline. The package includes a probe tip and user manual; no additional diagnostic software or wireless modules are supplied.
